i'm scared

Post by **eastcoastchaos** » Fri Sep 12, 2003 7:04 pm

let me paint you a picture. i'm bringing a friend of mine back to his house after some wendys, due to some moron who does not know that i had the right of way, i had to floor it to avoid being hit. i was in first gear and it felt like i was in a civic for a min. i damn near got hit b/c my power was suddenly lost. i tried it again later, and nuthin, absolutely no power band it just slowly crept up to speed but never really had any push. i have no idea what happened, she still drives normal unless i put it to the floor. for some reason my normal power increase, around 3500 rpm-7000, is gone. please let me know what you think it is. this really sucks

Umm...yeah thats not good man. I can tell ya one thing though, you'd know if you totally blew your engine. I wonder...you MIGHT could have caused the timing to skip a little bit (unlikely) and now it's off enough to kill your power. I dunno, I'm probably just making stuff up at this point

Post by **4felix20** » Fri Sep 12, 2003 7:04 pm

how about giving your MAF and throttle body a cleaning with some aerosol carb cleaner. i wouldn't really know....couldn't hurt though.

not 100% clear on your problem.

Are you saying the car bogs & doesnt want to run when you floor it and ONLY when you floor it?

if so.. I would suspect that it is either the MAF or a fuel problem.. I.e. Worn injectors/ Fuel pump not putting out enough fuel.

...and if it's bogging down all over the place, you might have bigger problems... smell your dipstick for gas and check your coolant for oil, etc etc.... If its not the easier stuff it could be rings or headgasket? Then again it could always be just a loose hose someplace or whatever, so dont panic just yet.

ahhhhhhhhhhhhhhhh, well out of the 4 of you that responded, i thank you very much. i gently cleaned the MAF, then went for a drie and gave her hell. she's as good as new. thanks again fellas.

Post by **XCrunner19420** » Fri Sep 12, 2003 7:04 pm

I swear the damn MAF is the cause of 50% of problems, well atleast mine...

Post by **4felix20** » Fri Sep 12, 2003 7:04 pm

how did you clean it? with just a rag?

Post by **Nismo_Freak** » Fri Sep 12, 2003 7:04 pm

Use brake cleaner... carb cleaner will leave deposits.

Post by **eastcoastchaos** » Fri Sep 12, 2003 7:04 pm

i just used a tissue and rubbed it clean, i'm not even possitive that is what fixed it. i don't know

Post by **eastcoastchaos** » Fri Sep 12, 2003 7:04 pm

well ****, it did it again. i guess it's not the MAF. what else could be causing the problem. sometimes it's slow sometimes it's fast, what can i do.

Run a compression/leak test. Make sure your timing is correct (A 240SX will run slower than a geo metro if the timing is retarded too much...trust me I know--and testing the timing would mean investing in a timing gun:pface). Umm...I know theres something else, but I just woke up and my mind has fully restarted;)...

Electronics are so evil...I'm glad to hear all is well!

Post by **eastcoastchaos** » Fri Sep 12, 2003 7:04 pm

"I'm glad to hear all is well!"

no no, all is not well. now every other time i go driving it runs slow as all crap. then 5 min later shes back to her beautiful well running some what fast self. i just wish it could stay consistant

Post by **k6kicker** » Fri Sep 12, 2003 7:04 pm

perhaps your intake butterfly isn't opening up all the way due to a vacuum leak or some other oddity.....

Ahhh this is why i love my 1980 Datsun.....no computers to crap out on me.

But as for your problem check your fuel injectors. My fiance's car was doing the same thing you said your is. We changed the fuel injectors and all is well now.

And if you need injectors, ive got a set i could sell ya cheap

Post by **midwestdrifter** » Fri Sep 12, 2003 7:04 pm

you havent by chance taken off the emmision thing that comes up from the exaust to the air box? i have heard with that removed incorrectly the car can act the way you are describing.

Post by **eastcoastchaos** » Fri Sep 12, 2003 7:04 pm

maybe just injector cleaner would work? i have a new fuel filter and i tried the injector cleaner a little while back. i'll go check all the hoses out

Post by **Altiman94** » Fri Sep 12, 2003 7:04 pm

I would check your timing. I drove a vtech 4th gen lude and it was dirt slow with the incorrect timing specs. After fixing that, boy did it pull.

Post by **eastcoastchaos** » Fri Sep 12, 2003 7:04 pm

but it doesn't happen all the time. i think if it were a timing problem it would be consistantly slow. i just got back from driving and it was fine, but i'm sure it will act up again soon. idk f-it

check your egr system. check for vacuum leak also. sounds to me that's your problem right there. and do a full tune up

crazy, my name is ben too. well i found a little crimp in one of the hoses coming from the intake that i un-crimped. i'm not possitive that was the problem but for now it is running like it should

Post by **soilwork240sx** » Fri Sep 12, 2003 7:04 pm

this is funny because my car is having the exact same problem. sometimes it runs good, sometimes its slow as hell. when mine is running slow, it sounds as if the engine is having trouble breathing and when letting go of the gas pedal, takes longer for the rpms to go down than usual. i had this problem with an old trans am and ended up being a clogged dirty cat. might wanna check on that.

Post by **drifter_for_life06** » Fri Sep 12, 2003 7:04 pm

research it some if it isnt fixed, theres a lot of options that could fall into play here, try a search on your problem, maybe somone else had it and psoted about it somewhere

it's not the cat b/c i don't have one. how do i re ground the maf

Post by **phil93_93** » Fri Sep 12, 2003 7:04 pm

hey, i have a 92 240sx , and it does the same thing that your saying yours does. it feels real fast at like 3/4 throttle but when i floor it, it just doesnt feel like its pulling as hard as it should. its like you hear the engine working its *** off but your not going anywhere.......oh yeah i live in spring hill, like 10 min from port richey
