I've been trying to diagnose a cylinder2 misfire have tried all I can think of swithced plugs coil packs checked for compression and spark even checked for vacuum leaks still runnng rough I did notice that after it warms up if i keep the rpm's over 1000 to 1500 rpms it runs much better no misfire good acceleration but I let it idle no gas misses wants to stall slow take off, could it be some sort of sensor MAF, IAC or something??
