Ok so here it is ive put my motor back in after a freshin up. I messed with the wiring harness a little bit, unpinned the coil pack plug(harness side) and also the IAC( harness side) as well but Im pretty sure there where put back together right. That is the only things that have changed. The car starts up good for a few seconds then either dies or the idle goes from about 500rpm to 1200rpm up and down, also I can not rev the motor almost like there is no tps or something.

Things ive tried.... swapped coil packs with extra, also swapped injector resistor, ignitor swapped, I have a brand new tps on the car.

Please give me advice Ive been trying things for about a week, searched the internet and no one has a definite fix
