Hi everyone I got a 2001 ranger with a 4.0 sohc and its got 80 thousand miles on it and it has an off idle like when you watch the engine it shakes but rpms stay steady at 600 rpms at idle and it sounds like a miss from exhaust area so I replaced plugs, wires, iac valve, tps sensor, cleaned egr and throttle body, also ran sea foam threw it and I finally replaced mad sensor also no change I got no codes and I checked for vacuum leaks dident see any and also replaced pcv valve too can anyone lead me in a direction to finally fix this thanks
