i got my car back yesterday, after leaving it at the shop for what i thought was just going to be a diagnostics test. come to find out, my father-in-law had them fix it, and he even paid for it! while i would have liked to find and correct the issue myself, i didnt get the chance.
oh well, i didnt have to pay for it, so i'm happy.
from what i could gather it had something to do with a couple of very dirty fuel injectors. they must've gotten dirty when i sat them down after removing the fuel rail? thats the only way i can think they got dirty.
but anyways, thanks everyone for their input, and read my other post to find out what i discovered when i got the car back!!
