July 22, 20196 yr From cold start, car ran like crap. Pulled P0303 and P0304 fault codes. After about ten minutes, car smoothed out and ran normally. Don't want to diagnose by wallet but is the likely culprit a failing ignition coil? Any other possibilities that would fail both cylinders and then recover? Humidity has been off the charts here in New England and the car sat for a few days without being driven prior to episode.
July 22, 20196 yr you could idle the car when it's behaving normally, then, use a plant mister bottle to spray the plug wires and coil - monitor for roughness. you could pull the plug wire boots to check for oil. but yeah, waste spark means coil failure will always be 1 & 2, OR 3& 4
