Grand caravan 3.3 has a miss at idle and at highway speed but no check light
Thats weird, It should have picked up on this, but never the less things to check are...Faulty spark plug (s), Faulty ignition coil (s), Clogged or faulty fuel injector (s), Intake air leak, Fuel injectors harness is open or shorted, Fuel Injectors circuit poor electrical connection, Ignition coils harness is open or shorted, Ignition coils circuit poor electrical connection, Insufficient cylinders compression, Incorrect fuel pressure.
How many miles on it? Have the coils or spark plugs ever been changed?
