Hear are the problems:
I replaced 318 with 360 RT, running the 318 mopar performance mod. When cold, runs fine; after warm up, idle sticks at 1100 rpms after deceleration and is killing my brakes to stop - should be at 700 rpms. Under full acceleration, it cuts out power and have to back off on the gas pedal slighty for it to power up. If I accelerate slowly, no problems, but still loss of power. Idle will sometimes fluctuate between 500 to 700 like it has a nasty cam. Sync is set to 0.
Dealer DRB test shows 02 sensor at 0 volts when cutting out under acceleration and IAC set to 80 counts when sticking at 1100 rpms after deceleration. DRB shows Fuel injectors are getting a longer pulse during cutout, but 02 shows lean condition. When main fuel line is removed and ignition is turned on, squirts 3 pulses of gas and stops, which means I am getting a primer charge, but how about prolonged fuel?
Is my IAC getting a high rpm signal from the computer because under acceleration it goes lean? No one can figure this out and I am now broke ov
