Thanks for all the help. Now it once started it sounds perfect except that it doesn't want to idle. It will rev up just fine but once you let go of the throttle it kills itself. i adjusted the idle some and brought it up but that didnt help. you think the TPS or the IAC is bad?

it turns out it was installed right but i had a bad coolant temp sensor. that one little sensor controls just about everything having to do with fuel/air ratio, advancing/retarding of the timing and idle.
