Ok so now my idle is consistent drives great. Throttle plate has been moved to a more open position and tps was set accordingly. I hessitate when throttle is applied. I think it's the damn tps but not sure. It does not make the click when adjusted. Vacuum is at 15psi 850rpm. I open the throttle plate just a lil to make 20psi rpm is at 1000-1100. I'm going outside to go and read my damn tps voltages. Man i'm so close to have a 100% runnin motor.

Replaced so far. MAFdCASECUThose have solved alot of problems so far. This is the absolute last problem so far. Everything else is great. Pics will be posted later on tonight of throttle plate position.

there are instructions for throttle enrichment. You move the tps from left to right untill there is a click. Then it is set. Anyhow, That is where i'm at now with this damn motor. Also, getting my head looked at soon.

You didn't set tps voltage?The RB25 uses that to see if the motor is at idle or not. An improperly set tps can cause the motor to idle high.

i'm gonna research the voltage set. I'm on stock ecu by the way. You guys think a series 2 tps will work on a series 1 harness? I'm gonna find out today. Thanks.

I need to do this really badly to my car, along with pull off the IACV and clean it. I haven't the clue how to do the TPS and voltage setting, so I guess I'm off to search.
