    Installed a new TPS and it has .97 volts now. But when I connect the IAC back up it starts running really erratic, it surges alot and stalls. I think the next step is going to be the IAC itself.

    E303 cam (I think)
    Sub-frame connectors
    I think it has a port job
    Might be re-geared
    Set up for nitrous (police removed it)
    Give me a break, it was from an impound lot, It's quick that is all I know.

    I cleaned the IAC too, looked like fresh oil on it, Maybe the engine has excessive blowby... It ran good for 2 min of driving then ran like crap.. Runs great with the IAC disconnected..
