Need injector help asap

[unknown007]

So after doing the plenum job I cleaned all my injecotors and ohmed them.Ohming them only told me that it has resistance but not if the injecotr is any good or bad.I ohmed them and all came up with 10-15ohms.I just ohmed then like 2seconds ago an they all omhed at 24-26ohms. What could be wrong?

If your gonna come in here posting B.S.,you know who your guys are,don't because I am not in a good mood and I careless about you posting B.S. like you should've had a pro do it.If thats what you think you know what you can go do with you suggestion.

Other then getting that clear please if anybody can help me.I'm not trying to replace the injectors cause if that's the case the cars up for sale and I'm off looking for another Q thanks.

Why I always recommend a REFERENCE RESISTOR [say 12 ohms with a +- 2% tolerance 12.24 - 11.76 ohms]. To check VOM before and after testing an injector.

Common for the battery in a VOM to wear out and cause error readings. The absolute worse case position on a VOM is lowest resistance scale for sucking an internal battery dry fast.

Important to understand HOW a VOM works to read various parameters and how the VOM device can fool you with internal errors.

Realistically you cannot trust a reference resistor because 1 in million may be mislabled. So you buy 2.

The reason the FSM say 10-14 ohms is because of potential bad batteries in VOM at dealers. Every injector should read perfectly the same [ give or take a few tenths of an ohm] if it is stablized as to temperature.

I wish I knew what you were trying to say but to me it sounds like engineering type of speech. I used a Snap-on Vintage 6.0 incase that has anything to do with it.

Try going to Radio Shack and ask them for a 12V resistor, they will know what you mean, then ask them how to test it if you don't know.

Check the battery in the OHM meter AKA VOM.

Engineering speech, I hope so as I have both a BSEE and a MS plus just for chuckles an MBA in Finance

People should not be using tools if they don't have training in theory and mainteance.

Even the RadioShack kid will think "what an idiot" if you ask for a resistor by voltage.

Public Bill 105, passed by Congress on July 12, 1894, made the international ohm the legal definition of the ohm in the United States.

It's very simple English recommending you check your instrument against a known specification resistor to calibrate it.

Celebration of one's own ignorance fueled by cultivated laziness is inappropriate response to someone who is trying to help you.

Maybe your next vehicle should be less complex, look in the yellow pages for the nearest Schwinn dealer.

The last three posts are an excellent example of how unneighborly NICO can be. Don't waste your time-no one wants to read this condescending crap.

If all the injectors had similar ohm readings on one occasion and the same but different ohm readings on another occasion then it doesn't matter what the reading is. Temperature affects ohm readings so coucl be that.

[elwesso]

Did you have the doors open or something on? That will skew the numbers.

I wouldnt be worried about it so much.

As Andy said, as long as they're all ohming in the same range, about +/- 0.5 ohms, then your injectors are fine. It's either a low battery in the voltmeter, hot injectors/engine (ohm in the morning), or you had the ignition in the ON position (pull the key).

Try going to Radio Shack and ask them for a 12V resistor.........Check the battery in the OHM meter AKA VOM.

Why I always recommend a REFERENCE RESISTOR [say 12 ohms with a +- 2% tolerance 12.24 - 11.76 ohms]. To check VOM before and after testing an injector........

In layman's terms, what Paul and Tech are saying is go to Radio Shack and buy a couple of 10 ohm resistors for about $1/each (and volt meter batteries) to check the accuracy of your voltmeter prior to taking any measurements. Touching the voltmeter probes the ends of a 10 ohm resistor will give a reading of 10.0 +/- 0.5 ohms (Radio Shack is only 5% accuracy). If you're within that range then you know the injector readings are correct.

I keep a 10 ohm resistor taped to the face of my voltmeter. It makes it very easy to verify accuracy and you never have to search for the resistor in the bottom of your tool box.

[unknown007]

Thanks for the people who helped but I think I'm good.Ohmed the injector 1 and 2 on the front of the plenum and they ohm 12.8 if I'm correct.Phew that was close.Maybe needing a KS harness or need to push the plug or double check to make sure it's on right.I apologize to Nico and everybody else who has to read what I had to let out but seriously they both are pissing me off.Just one day they'll need help and well we'll see.Well this thread could be closed or I dunno thanks guys.

Nobody taking AP classes wants to have the special ed students sitting in class wasting their time either......same with having dummies in one of your college classes.... Always a clash when you mix different education levels in same group,frustrates both parties.

And I thought I was the only one that did that

And I use a Very old Analog meter !!!

Still works like a charm !!

Yeah I'm ignorant but it amkes you look more of an ignorant replying talkign sh*t to an 18year old who works on his car more than your lazy a**.Anyways just stick to what you do best which is living off unemployment,sitting at the computer looking on what to leave a bad comment on,and yeah basically being a low life d!ck.

Maybe your next vehicle should be less complex, look in the yellow pages for the nearest Schwinn dealer.

Yeah if you buy it.I'll stick into getting a new Q since you keep riding the train. with BRIAN PETERSON.I suppose you do are like ****'s or something cause you also post one after another.

Special ed student?I bet they are smarter then you dumb a**.Don't make fun of special people either cause one day your gonna get your wife pregnant and your gonna get one.Ha might not even be your kid either.

AP english?Who takes that class?I sure don't you must be talking about your own kids.Sorry.

[jimbyjimb]

I'd say the big difference is that you don't have to come to unknown's classes. And it would seem that, unless you have something pertinent and not condescending to say nobody who attempts to assist this kid wants anyone here who acts as ignorant or belittling as a bunch of lame old men that like to talk down to others to make themselves feel good about being old and crotchety. Instead of attempting to tell this kid what a tech school would give him something useful in his language, or simply click the back button unless using the mouse is beyond your aging motor skills. Then hit "backspace" unless that is also too complex. The truest mark of intelligence is taking something complex and simplifying it. It's also the truest mark of understanding. From some of the more belittling responses it is apparent the poster of said response either doesn't really understand the topic or isn't that smart. Giving the kid overcomplicated answers one would provide to a fellow engineer or experienced technician is obviously of little help considering he hasn't had time to become either. So, in not providing the simple get 'er done info he needs you yourselves have proven to be of little use to anyone but your own ego. SIMPLE. S-I-M-P-L-E. Get it?

Like some other posters, nicer and more level-headed posters, have said: As long as the values are similar dont worry. If the car runs obviously some work, and if it runs and all are testing similar the unless there is a mechanical issue the injectors oughtta be fine. If there were 7 that were similar and 1 were odd then further testing may be required to determine if that one were bad. Follow? You can apply that to just about anything. Sorry some of us have the attitude of kniving snotty children.

Don't prove their point for them, it's just a forum. Just concentrate on those who would give you suggestion or advice in a friendly manner rather than waste time and space chastizing you like a child. Many of these more bull-headed users say things like they say because, in their way, they're trying to help. Some just don't understand their way is really in need of counsel and a good lay. Then maybe we could all chill and have a civil discussion to the benefit of others. Which is the point to this forum, right? Am I wrong? Somebody please correct me if this forum is here to serve as an ego booster or a method of chastization? Constructive critisizm is one thing, focus on the CONSTRUCTIVE. Anyway, the good intentioned people here make it worth spending time, so try to focus on that. And really, don't outburst so vulgarly. While I personally understand, it does nothing but disappoint the people who are trying to help.

[96Qowner]

One of the really cool things about a forum like NICO is that everyone's posts are permanent.

If you feel like acting like an A-hole one day, that post is here forever, and you look like an A-hole forever. If you read the forum on a regular basis, you soon recognize who's helpful and who mostly pops off, like he's your dad or something, like his irrelevant opinions actually matter to you. Sometimes, they can't even spell in their posts, or can't even correctly quote another post, don't see any need to edit their mistakes, etc.

They define themselves, all by themselves, and it'll never go away. Watch and learn. Try not to make the same irrelevant ego-based comments yourself.

That's what I do, at least. Why get in the way of people who insist on making a$$es of themselves? It's much more fun to watch 'em do it all by themselves.

^^^^

That sounds like the culprit. Years ago, when I was following Wes's instructions for checking the injector coils I left my door open, which left the dome light on. That skewed the numbers.

So, make sure all doors and trunk lid are shut, nothing is connected to the 12v socket (like iPod), and the key is removed from the ignition.

I've been using the same $10 digital China-made multimeter from Wal-Mart for the past five years.
