okay so ive cleaned my IACV a few times... reset the ecu each time, and still have issues with it... i can drive it some days with no problems, and other days it acts up... the idle will jump back and forth very fast from about 1200rpms to 1300rpms... and when i start to drive, the engine behaves violently... from a stop it takes alot of gas to get going and between each shift the rpms go down instantly causing a very rough transition... ive replaced the IACV with another working used one straight off of my friends car and it still has issues... could it be the plug itself?

fyi its an 01GSR obd2

 

may have a air leak (test with carb cleaner) , or a crazy *** air bubble in your water system.

condition of spark plugs/cap/wire...
valves...

if you did anything to the car as in MSD and such..replace with stock to see how it works out.

Good Luck

you may want to try swapping out tps (throttle position sensor) with one that you know works. This may also be the culprit
