Ok, had this problem for a while now. I have a 2000 TA. Stock LS1, flashing SES light. I threw a code reader on it, it reads P304 (random misfire on cylinder 4). So I changed the spark plugs, wires, and number 4 coil. I can smell it running rich. It idles sometimes, dies most of the time. Runs like a champ at wide open throttle.
New Plugs, Wires, Coil, O2 Sensors.
Tested Spark, and injector.
Could not hear any kind of unusual noises while it was running (other than the rough idle)
Got to check the compression, so hopefully that tells me something. Any other ideas?
