Alright well my SR will turn on and it can stay on IF I keep pushing the throttle down constantly, however, once I let it go it starts dieing and won't stay on, so I cleaned the IACV and the vacuum lines are brand new. I did search but my question has to deal with my ECU, I know its chipped, however, I dunno what the settings are on it and to what MAF or injectors and such its set for. Right now the injectors are all stock, and MAF is from the SR, so would the ECU settings affect this issue of not being able to stay idle?? I even tried unplugging the MAF and still dies if I don't push the throttle.

i had this same problem recently. cleaned the iacv (took forever to get to) and cleaned the maf with maf cleaner, changed spark plugs, and so on for a minor tune up. check the timing. that made worlds difference for me. bought the craftsman timing gun and set it to 15 degrees. adjust the CAS. hope that helps. also try adjusting the TPS and the aicv. good luck

Yea I cleaned out the IACV today but did't do too much, the timing I've done at least 5 times so I know its good, I just bought new spark plugs today which I will put on tomorrow, I guess I'll try cleaning the MAF tomorrow as well. Thanks for the tips

Yea I searched and I know about those cleaning procedures, but I just wasn't sure about the ECU tune affecting it
