ok problem..I have an 87 TII and for some reason it doesnt want to stay running..i was doin a pull at like 8lbs with no exhaust on just downpipe..and then after i let off it sputters and dies..so i just thought that i blew off intercooler pipeing..but check all pipes and still connected..and then tried to look at all vaccum lines and they look good..

when i try to start it it starts up and then jumps to like 3k for like 5 sec and dies..i heave to give it gas to stay alive..i know that cold start jump it up but it usually only jumps to 2k but its also warm..

what could the problem be?

does it run ok if your tring to drive it around or does it miss and sputter all the time?? is it really hard to start??

 

ya it sputters and stuff and its hard to start

 

yea. the same thing happened to me not to long ago. i have a n/a 88 gxl. my car is still sitting. and i think is might be an apex seal. since it doesnt want to stay running, this means it might not have compression leading to this problem. thats what i think.

crooked.

 

its a vaccum leak!...but i cant find where its coming from...hmmm

 

how does it drive going down the road, like say if u floor it does it run normally or still sputter like crazy??

 

Vacuum leak. Take carb cleaner and spray it on all vacuum hoses and connections when your car is running. You'll know it when you find the leak(s).

 

when im in boost it runs good but as soon as i let off and its in vac..sputters

 

it has to be a really small leak if your actually getting boost

how much boost are you getting

and do what inflateablepets said to find the vac leak

 

i dont know how much i can get i just took it to like one lb to get it home without sputtering..im checking today though

 

Check the TID, how ever it usually will die in boost if the TID is ripped.

 

thanx guys for all ur help..i found the problem though..

i noticed that the brakes where not working either and so then it came to me that my brake booster vac. line blew off..

so that was the problem..it simply blew off and so i put it back on..

haha..

so anyways thanx for the info..

 

glad you figured it out that would do it, you can actaully build boost with quite a few vacume leaks. i wqs still able to make 13 psi no problem with like 3 vac lines open

 

haha..ya i cant clamp the hose good so its still a small leak and now i idle at like 300...GAY
but thanx for the imput..
