Ok i have a n/a 93 talon 4g63 ant i started noticing that when engine is running temp it has a very erratic (ruff) idle driving is fine till stopping then idles ruff and almost wants to stall just replaced plugs and wires and did a compression check (just checking for a blowed head gasked due to coolant loss) all good checked for spark arcking no arcking also hooked up a timing light to all wires to see how the spark paddern was and when idling ruff all 4 have a erritic spark where should i look next? Coil,o2 sensor, maf sensor, or maby cam sensor
