I am having rough idle, causing cylinder 3 miss fire (p0303). Ran through 2 tanks of seafoam I have rotated and replaced the spark plugs and wires. Replace fuel injector on #3 cylinder, ignition pack, throttle position sensor, throttle control sensor. The mechanic did not find any vacume leaks or issues with the O2 sensors.
have the same problem?
