And i can't figure it out for the life of me.
The car went to maft pro recently and the set up is done right... aside from this miss. I do not know if i had it before either, it has been a long time.
So basically my AFR'S are good, it is just when i hold the gas, you can hear it missing, as if it is going to blow up or something lol.
I had oil in my galley, but that was due to the galley bolts being loose and shooting up a bit of oil. None of that anymore. Everything was cleaned up.
I did the spark plug wire trick by unplugging each, because i thought one of my wired would be fucked, but they all just made the car sound like a Subaru.
The car sometimes wants to stall, but never does. And this is all at random.
My Maft pro map reads -7.5 psi at idle, which is like -15 inhg of vacuum, but i do not think i have a leak... Anything anyone can think of that i haven't tried yet?
The car boosts to 7 psi as well, and last night i even beat an Sti from a roll. what do you guys think?

got a clip of the sound? BTW, vacuum should be more around -20inhg. If it were me, anything lower than 18 at idle i'd expect a leak ;)

also, does it do it on a cold engine vs. hot or both states?

This just occured to me.

Not long ago...(when i had an engine not covered in melted plastic and charred components :) )...i had a similar issue. It was actually and injector. It actually got unplugged when i went to mess around with the ISC. Same symptoms you are having. Its something to look into

will do tomorrow. Nothing helped today.
My mechanic said that an injector clip being unplugged would fuck it up, same with a clogged inj.

like i said ;)

the car WILL run and drive, just kinda shitty. though For being down an entire cylander, personally my car drove pretty damn well lol
