yeah i have a surging idle problem while in neutral. i cleaned out the IACV and the FITV. worked no wierd idling for the rest of the day. the next day the car dies on me. so i call my friends mechanic he says check the plugs...find out i got oil in the first, second and third cylinders. so i take the valve cover off and replace the gasket and the gommets and the spark plugs and the cap and rotor just to do it and it was fine for the rest of the night. then on the way to a friends house it died on me 3 times. im gettin frustrated. so bottom line is can someone help me with a leakdown test?
