hey guys my 94 celica st when hot or cold will fluctuate its idle. it will bounce up and down about 200 rpm and when listening to the exhaust it sounds like it misses every once in a while. i bought new spark plugs, spark plug wires, front o2 sensor, fuel filter, and i took out the throttle body and cleaned it all up. well mainly the butterfly i didn't try taking off the IACV and cleaning it. As a side note i do not have any check engine lights on, and yes it does work.
Any ideas on what it could be? |

take the IACV apart and clean it if you haven't. test the Coolant Temperature Sensor with an ohmmeter, look up the specs in the manual in the stickies. make sure your accelerator cable is mounted properly on clips and not laying on the exhaust manifold. You may need a timing light to set the ignition timing. and how old are the plugs, wires?
