ive had this nasty idle problem with the car, its an 86 2.8L A4 sport coupe. doesnt run too bad at all, we just fixed the distributor oil leak. we start the car and it barely idles and we need to keep the RPMs a little up for it to idle, if we shift it into gear too quick it will stall out and die. once it warms up we can shift it into gear fine and it runs really good. its just before it warms up when its bad. it feels like its a dead spot in the low rpms when its cold. the car isnt registered since we just started working on it, so we cant drive it to go get codes taken from it, if its throwing any.

does this sound like something framiliar to anyone? vacuum leak? some kind of sensor? any help appreciated, thanks!

 

My 305TBI did that when my fuel pump was taking a dump on me.

Id check your fuel pressure.

 

thanx for the reply, ill add that to the list lol

 

how should i check the fuel pressure? i figured my dad would know, but he never checked fuel pressure on a fuel injected car. tell me what i should do to go about checkin this thing lol. im searchin the posts now, and lookin through tech articles, so if i find what im lookin for ill edit this but until then any help appreciated
