update: EGR and/or EVS!!!!!!
alrighty...first i want to ask about the throttle position sensor....what would the car do if that little fart went bad?? my car is acting weird (different anyways...maybe it's running correstly for the first time!) i had similiar symptoms with my standard t-bird awhile back, and after i replaced the iac valve, all was well.....but this time, unless i have TWO bad IAC valves, it's something different. first of all - i replaced the supercharger, inlet plenum, and throttle body off my parts car (in one piece, so i wouldn't have to mess with the gaskets) the only sensor from the parts car is the tps..... today i cleaned the EGR valve because i got a code saying it wasn't opening...i need to scan the comp again now but these symptoms still remain:
SYMPTOMS:
car will idle decent (sometimes slight fluctuations) but if i press the clutch in it will idle at about 1500 rpm...it used to idle at 1000 rpm in this case, and 750 at a stopped-car idle
when coasting...the engine will cut out a little, slowing the car down slighty....it feels like the iac valve is messed up....it's just like the air flow gets cut and then when i press the gas pedal a hair, it snaps open again. (the car either speeds up a litttttttle bit or slows down a littttttle bit when coasting) like i said, on my other tbird, i replaced the iac and it stopped, i did some iac swapping this time....and either neither work now, or it's something else.
hope someone can help me out, sorry if this post seems jumbly...i'm in a hurry to get back out there to the garage!!! thanks guys, happy easter!!!
