I think I might have a moderately burnt exhaust valve. I keep having a slight miss fire at idle, even though the ECU has no codes and all the sensors are good. It smooths out a bit when the engine warms-up. The engine runs strong with zero backfires. The previous owner drove it quite a bit with a bad fan clutch. It always ran right before the overheat (red line) mark if he drove it in stop and go traffic. A dumb mechanic told him that it was just a miss-read of the temp sensor. Well, after changing the fan clutch, it never ran hot again. I also already installed a new fuel filter and changed all the ignition components. The engine has 160,000 miles.
If I do have a bad valve,there is a newly rebuilt 7120 head on ebay for 269 bucks and free shipping. Will that work on my 96' engine without any issues?
Mine has the two coolant temp sensors. One for the ECU and one for the gauge.
