can reset code but it comes right back. Engine misses all of the time. Replaced plugs, no change. Inductive timing light will flash rapidly on cyl 1,2,and 4 but on 3 sometimes no flash or very sporadic, plug wire measures about 2000 ohms. Reconnected throttle pos sensor and the connecter to the coil module...no change. Suspect a new coil module will fix it. What do you think? no problems with the engine running untill this happened...ie no warnings or other unusual symptoms. Thanks Larry

A misfire in a specific cylinder should lead you to check the spark plug, fuel injector and compression.
