87 iroc help

I finally got it registered thursday(insurance sucks here is boston, ma) and to it for a spin yesterday(would of drove it early than that, but i needed to replaced the alternator, which i did saturday). So i was driving it around, test driving it to whats up, and after awhile it just stalls. Now i didn't give it a full tune-up yet, which i'm hoping thats the problem(don't know what the sparkplugs look like) but i was wondering if there are any other solutions to this aswell. It runs fine but it just wants to stall, i was also thinking maybe it the fuel delivery, i'm just not sure...

oh and it's the 305 btw if needed

when it stalls, does it turn back on or do you struggle to start it back up? because i was just reading another thread and it came to my head that it could be that you have a broken hose line and your car could idle low and then just die out

It starts right up fine, no problem there. Just after it starts, i rev it alittle and as soon as i let off the gas it stalls. My first problem was the alternator wasn't charging the battery, fix that problem, and now this. Man i love chevys.

I doubt its as easy as a tune up...Although that won'tr hurt...

Have you checked to make sure you have all good vacume hoses? (No leaks there?)

what about the fuel filter? it is fuel injected?

im sure his car isnt fuel injected

Yeah it's fuel injected, (TPI i assume is fuel injected) i didn't checked the vacuum hoses which the guy i bought from said need to get done up. I also have any exhaust leak near the catalytic, which could probably add to the problem. it will idle for a while then stall. And everytime after that, starts up no problem just let off the gas and it stalls.

well i said your car wasnt fuel injected so im WRONG! but yeah i saw that you "assume" its fuel injected, you should probably take it down to a shop and get them too look at it once and for all
