s/c problem! what could this be??
Last night me and my mechanic installed my vortech s/c and Accufab TB/plenum and everything was fine. it started up ok etc. when we went for a test drive i shifted from first to second then third, but a sharp turn was coming up so i shifted to Nuetral then the car lost idle and went dead[]. We later found out that it has trouble keeping its idle. It keeps its idle when it first starts up but as soon as you give it some gas it revs then instead of going back to idle it dies.
I just test drove it tonight and when i would even lightly touch the acclerator the car would jult uncontrolably. Last night we figured out that it could be the Throttle Position Sensor because we took it of and put it on the Accufab. what do you guys think.
Thanks for your help

how is the TPS damaged when removing. my mechanic said it took him almost a half hour to get it off the stocker.
I just got a new one but i cant get the friggin bottom screw off it looks like it is stripped. why cant they make flat heads.

I've heard that the TPS and it's screws get message up easily. I bought a TB/Plenum from E-bay and when it's TPS is installed on either of my TB/Plenums (OEM or E-bay) it throws a error code on the CEL. So the E-bay TPS was BAD. When I use my original TPS it the code stops. I've never had that screw problem. I would start with the TPS. I hope it's something simple.

Could be lots of things....depending on what S/c kit you bought from Vortech....POSSIBILITIES:
With my procharger I had 10 psi of boost..so it didnt need a replacement of fuel injectors because of the fuel management unit it came with..but I bought some 30 lb injectors anyway and installed them. And whats happening to yourcar started happening to my car...turn on...fine...drive off... fine...park...idle low and then it would turn off. So I put my old injectors back on and the problem stopped. I was running to lean...so I needed to buy a 75 mm MAF sensor...and installed the 30 lb injectors...and everything was fine. So it could be that you're running to lean for some reason or it could also be any number of sensors...preferably the TPS as said before....but doubtful.
