Fuel Injector

[jimbyjimb]

A. I probably have WAY more experience than you, so don't talk down.B. My KS are not dead and I was and am not interested in replacing good known parts, the reason, as stated to anyone literate, is that the bodies are cracked, not that they don't function. Cracked bodies means they will fail and probably soon, so I decided replacement was a wise move considering imminent failure. Duh. Why replace a harness undamaged? Found a frayed wire in the KS harness, also a tell-tale sign it needs replacement. Most people unnecessarily replace parts out of fear from inexperience. I have neither, so if I replace something it is because it needs to be. Pulling a Q plenum is SIMPLE. This is not a complicated engine. I DO NOT FEAR IT. Therefore I do not unnecessarily waste money on things like brand new factory high quality injectors doomed to death early because of ethanol. Why not rebuild them or r/r cheaper when they WILL ALL DIE YOUNG? When and if there are successful tests performed on a different injector I will replace if worth it as far as longevity goes. You make it sound like I was intent on holding a hose in my valley for kicks. Obviously I know not to flood a valley. Duh again. My ohm meter works fine and my KS work fine. For how long with cracked bodies? LOGIC. No reason to waste a 200 dollar injector when it will probably not outlast a 50 dollar in a state that will probably be soon switching to 20 percent ethanol. You only critsize my methods because you haven't the experience or skill to actually understand or do what I can. I have the facilities, knowledge and equipment to r/r my intake for an injector swap in a couple hours or less. It is an easy task for someone with any reasonable experience or mechanical ability and fiscally makes more sense than wasting money on an unproven cure. I have stated in the past that I don't care if I have to spend a weekend day r/r plenum especially since the doughnuts are re-usable to a point. Practicality is something that comes with experience and understanding. When I fail I understand why and I understand the consequences of alteration or cutting corners and thus am not surprised or worried. I'm sorry you lack the experience to understand what is happening here. I'd suggest reading and learning. As for information seeking I am not above asking less mechanically experienced members for information specific to this car that I may not have or be able to find in past threads. Though in theory and attitude there are many here I disagree with and occasionally mock or critisize I do appreciate relevant useful info pertaining to the Q in specifics rather than such general commen sense issues as replacing gaskets or not covering electrical connections in fluid. That is bigtime common sense for someone who went through 3 years of trade school and 1 and a half years as a professional working mechanic. So I don't see how I was out of line calling you out. Come to me with your experince and advice and explain how your methods would differ and I will counter on how mine make more sense to my specific situation.

I know I said I wouldn't come back, but since you are calling me out. If you can read and have tools, you can be a mechanic, especially with this site. I am not impressed by your "resume" first of all. "Mechanics" get dogged on this site all day long. Secondly, I highly recommend you do more reading than you do writing, as you quibble over moot points. Although members standards may very, your methods are nothing short of ghetto engineering by anyone's standards, and you will pay for them unless you flip that ride. I try to help people on this site because they have helped me so much and I tried to help you, but I guess no good deed goes unpunished. My 94Q is worth well over eight grand. Where's a pic of your chain guided Q FNG? Lets let our cars do the talking, since I have better things to do.

Obviously you are the sort that is pious and arrogant enough to assume because you know a box end from an open you are an expert. YOU are the one quibbling over moot points that YOU brought up, pointing details a retarded monkey would have figured out and pushing the envelope to a tear. Nobody needs someone following them around calling out common sense issues such as "look both ways before crossing a busy intersection" or "replace used gaskets" or "make sure not to cover electrical components in water and glycol." If you think anyone this day in age will pay 8 grand for a Q45 anything less than a 00 YOU have delusional issues. You have an apparent lack of understanding you don't seem to be willing to change and probably just do the typical monkey see monkey do type of wrenching, which there is nothing wrong with, but it doesn't mean by any stretch of the imagination that you actually know anything. Just how I agree with statement anyone can do it, doing and knowing are completely different, like the 12 year old english kid with a baby. If you can't see that then you are truly blind. I also would like your resume and background on your hard, hard life to explain that you even have the slightest clue as to what "ghetto" is. You go take care of your "better things" as I would be more than happy to continue on my merry way. Just because you aren't capable or don't understand something doesn't make it bad or "ghetto." With every additional post you persist in making yourself look more and more foolish in persuing a fruitless dispute in which you have gained no ground. Know when to quit. And ditch the word "ghetto" unless you have some special title granting you some sort of knowledge on its actual meaning. It's apparent from your return you are simply looking for a fight, especially with such absurd statements as "My 94 is worth over 8 grand." If you think that, be on thy way and be happy, the truth will crush you when you attempt re-sale. Vehicles are not an investment and those who treat them as such will lose alot of money in the process needlessly. I'd be utterly shocked if there were a G50 on this earth that could fetch "8 grand" and I would be willing to bet there are many members on this forum with much nicer Q's than yours that won't fetch over 4. Think about it.

I'm sorry you reacted so defensively to adult critisizm in such an immature and defensive manner, but any "comeback" you've brought lacks any specific critiques that can be of any use to anyone on this board. And your misuses of the word "ghetto" are rediculous and offensive to anyone that has any first-hand knowledge of what that word really means. I don't imagine there are many in MO.

Guys, ease off! You both are better caretakers of your cars than most on this board.

Listening to youse guys is like overhearing two Bishops arguing over which one is more holy.

Now each should reconsider his remarks and reflect on what those remarks accomplished. Group hug!

OK, who cloned Brians screen name and used it in the above post!!!

"Hurtle the dead, trample the wounded" !!!

[jimbyjimb]

Perhaps there should be easing off, but I'm not off my high horse yet and I'm not done trampling the dead one behind me. Diagnostics are for professionals and are an industry accepted standard and parts throwers are not. I was critisized for being a professional and a diagnostician taking the time to examine good known parts BEFORE determining they needed replacement. I was also critisized for taking a more practical approach to the intjector issue rather than jumping in and throwing money down the toilet on an unproven solution. I am educated and have read and understand Heaths and Qtechs posts on the injector issue. There is no conclusive proof, through diagnostics, that there is any solution to this issue, therefore any money spent on replacing diagnosed good injectors is money thrown away that can be used on my gf's engagement ring or a nice vacation for us. It would take me 2 hours, at a snails pace, to r/r plenum to swap 1 injector when the next fails to be replaced with a lifetime warranted unit that I can replace at any time free of charge. Parts throwing, as suggested, is unproffessional, unaccepted by the auto industry, and hopefully an unaccepted practice on this board. It takes skill and experience to be a diagnostician over a parts thrower. I have been here a year and have been called out myself on BS and am not afraid to do the same to others. I have also been here long enough for older members to know that if I have a question or don't know something I am not afraid to ask or admit. Just like I asked about the dots earlier in this thread. The prior critisizm was completely rediculous an uncalled for.

I defended myself from an unwarranted attack on using diagnostics to reach conclusions rather than parts throwing. Perhaps nothing was accomplished accept my own defense. If I am going to be attacked I would like to be so with relevant facts and questions specifically to method rather than immature irrelevant statements and bogus claims. That is all. When my parts get here I will repost, in greater detail, what has been done. I am also taking pictures of re-assembly for use later if requested by any first timers or DIYers as I have the time to take.

Replaced all appropriate gaskets, hardware, all vacuum and fuel lines, heater hoses and coolant lines. New injector and KS harnesses, new KS, IAC hoses, coolant temp sensor, PCV valve, changed oil and installed new injector on cyl. 4. The car runs so much better now it makes me seriously want to consider a full injector swap, but it just can't be justified. yesterday the Q and I spent some quality time at 5000 rpm in 2nd gear on the freeway to clean her out. Seems to be fine. I figured the coolant sensor and heater hoses would be a wise move since I'm not looking to r/r runners or plenum again anytime soon. I have a backup injector ready to rock in case one fails.

Other news is that the Q is now no longer my primary vehicle. I bought a 76 Toyota SR-5 pickup, standard bed, as my daily driver. It's a 700 dollar special and needs alot of work, but it's all cheap because it's all Toyota. The Q will be used for backup transpo, trips and dates with my lady. Also, as a heads up, legislation is talking about an increase to 15% ethanol content, so join the coalition!

One panic stop on a rain slickened I5 with no ABS should send you back to the Q45 pronto!

I've been driving 1976 and older cars and trucks in Seattle for almost ten years, not much scares me anymore. The trick is to not drive like a jerk and follow the 3+ second rule at all times, regardless if the weenie behind has a kiddie-fit. My biggest concern is hills in the rain as downtown is dangerous period, but ever so much more with a truck that is a stick. Thankfully I have a fully functional E-brake, which helps.

Standard resistor values are +/-20% unless otherwise marked. 'Precision' resistors are +/- 10% and +/- 1% resistors are also available. So if no tolerance marking , it is +/- 20%

[qship96]

I remember when I bought my home pre-amp and amplifier, the owners manual boasted of utilizing 1% resistors, and other strange sounding components.
