fl327 Posted May 1, 2002 Share Posted May 1, 2002 ok heres what happened. i go to jump in my lovely firebird this morning, and it idles for a second, then gets rough, then eventually stalls, ive been fighting this for some time, once i resorting to running hi idle in order to get it to stop stalling, then i figured this out, MAF likes to have a solid connection with no air leaks and like to be mounted one way and one way only to run right, ok so i went to the plumbing store and mount everything really firm and nice with those turbo looking hoseclamp rubber things. ok runs alright, doesnt stall, still runs rough today i found the problem, there was a hole in the bottom of the air box that is attached to the throttle body, plugged that up with a small piece of tin rtv and tape, and boom, idles great i dont understand, yes i now the problem is gone, but why does the maf do that????? im trying to figure this fi out and its weird.

Tim240z Posted May 1, 2002 Share Posted May 1, 2002 Is that a LT1 firebird? Just unplug the MAF and let the computer default to MAP/revs. Tim Quote Link to comment Share on other sites More sharing options...
Guest Anonymous Posted May 1, 2002 Share Posted May 1, 2002 From what I understand it does that due to loss of vaccum. Basically there's an idle silinoid (a small stepper motor connected to you accelarator pump) which controls what the car is idling at. It does this based on the computer which is determinig where to idle based on input from the MAF sensor. Any vaccum loss and the airflow is not what's expected or the reading is not accurate which in turn confuses the computer. When the comp doesn't know what to do it just tries to fix itself until the car either stalls or you turn it off. It should be throwing a code when it's doing all tis. Is you check engine light coming on and blinking or anything while it's doing all this? Just some thoughts. Have a good one. Quote Link to comment Share on other sites More sharing options...
