is it a misfire? does the car wobble at idle?
agree first cheap call is replace fuel and air filter, then take the car for a plug in diagnostic test?
dudesky: could he do the old spark plug test by removing a coil lead one at a time, then when removal does not change the roughness of the running you know its that cylinder (1-6). ? Maybe this would hurt the ecu, I dont know.
I'm desperate for help on my ews issue if anybody can help
