Ive read so many threads about idle stumbling, and they all seem to be vaccum leaks... heres my situation.
First off my car is an s13 coupe, with a redtop sr20det motor....
...The car starts and idles up and down in between approx. 300-600rpm untill it dies shortly after. If i unplug the maf sensor, then the car idles like its brand new.
Ive checked every vaccum hose,
checked all the couplings on the intercooler pipes replaced a few that were questionable.
Checked to see if my blow off valve was leaking at all.
Sprayed Starter fluid on all possible spots that would/could leak(including the injector grommets)
it has a new intake manifold gasket, and a new throttle body gasket.
My brakes work fine, so the brake booster line isnt leaking either...but i check that for rips or holes anyways.
My last suspects are the collector Gasket on the intake manifold, because ive never replaced it and ive had the Intake off in between 10-20 times reusing that same gasket(ive heard since its metal it doesnt need to be replaced?), I also sprayed around that with the starter fluid and got nothing.
I also think it could be the aicv or whatever that idle control valve is on the intake... I had it off a long time ago and just reused the gasket, but it worked fine since then. I swore it had something to do with my injector grommets, but when its idling, it wont do anything when i spray starter fluid on them.
Its kind of odd, It ran fine, then i replaced the clutch one day, and i took it out down the street...it ran funny, and now it idles wierd... and seems to have a boost leak.
SOmeone Please help me out, this is driving me insane.
