welcome to the forums. So you took the entire system off so it was breathing right from the throttle body? Or you took it off from the MAF forward?

it took it off from the throttle body and it ran perfectly no sluggish response..when i have either the stock or aftermarket ones hooked up its sluggish and tries to die

That's interesting. You have disabled the MAF sensor and it runs.

I can imagine it could run at idle that way, since the throttle body is closed and the air bleed valve is controlling the idle speed/mixture. It should die if you open the throttle body.

My guess is you have somehow damaged the MAF sensor.

yeah i can rev it up and drive it around the yard with it all off. so it is a damaged maf? thats what i was thinking how much do one of those run

You should be throwing CEL's with it off...

krispy · April 22nd, 2008, 05:21 PM

nothings on unless the light is out or something...could that be why its sluggish on take off and tries to die and everything? Because of the MAF?

I don't understand how it can even run that way, at least above idle!

The MAF is supposed to measure how much air is going in the intake and adjust the amount of fuel from the injectors to keep the mixture right. If the MAF is damaged it could make the engine sluggish since it wouldn't get the right amount of fuel.

I think a new one would be around $100, maybe less.

alright thanks and that could also be why i smell gas every once and a while from too much being delivered? well thanks for all the help this really helps me out i appreciate it from all of yall

Alright well i got a new maf from a buddy and its running great thanks for the help that was the whole problem in the first place

stephen · April 23rd, 2008, 06:25 PM

I looked into this some yesterday.

If the MAF is disconnected, the computer goes into a mode where it generates a MAF signal from the engine RPM and throttle position. So the car should still run with the intake out.

dgt_mustang · April 23rd, 2008, 08:42 PM

that last bit of info from yo stephen is interesting, i never would have geuss or even thought about that.
