No acceleration!!!!!

[eazy_e6996]

Ok I could quite find a thread that had my problem so here goes. 96 camaro mt, 3.8 v-60000 I loaned it to my brother for a couple days and when I got it back it kinda flooded when it first cranked then smoothed out some but when I got in to drive up the road if you accelerate past 2500 it just chokes and falls on it face. hmmm? but its got progressively worse nafter a few days it barely will crank and idle either goes way low and chokes and dies or idles up to about 4000 rpm but the instant you touch the gas spit pop sputter and dead?? I'm at a lose I though maf sensor I looked at the elements but they dont appear to be damanged so IDK? help please! me love you long time:naughty:

Re: No acceleration!!!!!

check your fuel filters they are probably all clogged up. is your ses light on or flashing.

Re: No acceleration!!!!!

...almost sounds like what mine did when the cat broke and clogged up.

Re: No acceleration!!!!!

Re: No acceleration!!!!!

I agree with the plugged cat suggestion.

Re: No acceleration!!!!!

Nope mine is catless and no lights on either I mean its not a hesitation it absolutly wont accelerate and it was over a one day time period from running good to running like shat. I took the TB off and gave it a good cleaning but to no avil so thanks but any more ideas?

Re: No acceleration!!!!!

Bad O2 sensor? I hear those don't throw codes sometimes.

[eazy_e6996]

Re: No acceleration!!!!!

yes it is opening and I dont think an o2 sensor could cause this much damage. What is the operating fuel pressure for my car I'm gonna check it next oh and also when you first crank it, it has a loud sucking sound like every vaccuum line on the engine is off its always done this but it usually goes away after just a second now its constant and if you try to rev it, it spits and pops through the intake when its cold anyway

Fuel pressure. Same thing happens when you run out of gas.

Re: No acceleration!!!!!

you mentioned that it flooded for a brief period, check your plugs and see if any of them fouled. my .02
