are you misfiring? This was happening to me the other day and the car was misfiring because of a broken wire on my OBD2-OBD1 Conversion harness. Try unplugging the IACV and starting the car. It should idle very low.

Is the CEL ON?

A bad IACV seems most likely.

Have you tried replacing the air filter or adjusting the idle screw on the throttle body?

thanks for the threads but it could not really help...my motor just recently got rebuilt which is an ls block with a gsr head...rite now its still an obd2 running on p2t si b16 ecu...could it be that i need to convert to obd1 and run a p28 with a good basemap for now since i kno getting my car tune will b pretty spendy...

i do have a cel but its for the second 02 sensor and knock sensor...but when i cleaned my iacv, i tested it with power and ground to the pins from the valve and it would click...wouldnt that tell me that its working...the air filter is new which i just bought and as far as the throttle screw, how do i adjust it...which way do i turn it too and how much..does the iacv have to be unplugged to set it..

the iacv doesnt have to be unplugged. You turn it clockwise for lower, counter clockwise for higher. You need a flat screwdriver to do this.

Well, the ECU could be causing the issue, the second O2 sensor could also be causing your problems. As far as the knock sensor goes, i find it hard to believe its failed, its a rock, like a crystal, there isn't much to fail there.

ya ima soon convert to obd1 with p28 with a basemap from pherable tuning...also im pretty sure obd1 doesnt look for knock sensor and the second o2 sensor...
