Ok without getting into too much boring detail, the other night i began to dreadfully notice a "miss" in the engine. What are the many factors that would cause the engine to "Miss"? Any help would be appreciated...
I had a missing problem with my 3.8. It would miss throughout the entire speed range from street driving to highway driving. I replaced the spark plugs (Autolite copper to Bosch Platinum), the coil pack, and the O2 sensors (Motorcraft to Bosch).
Turns out the spark plug wires were bad, and they were cheap Xact brand cables.
Replaced them with Bosch cables and the problem went away and the EEC-IV returns a code 111, meaning A-OK.
I'm willing to bet that your spark plug wires need to be replaced, especially if they're cheapies. I didn't think my spark plug wires were bad because they weren't even a year old, but I didn't think about how long cheap wires would actually last.
The new wires, coupled with the other changes and the recent oil change with Amsoil Series 2000 0W-30 along with a power flush on my transmission, has helped my car run considerably better. And, the icing on the cake was replacing the manifold and tube assembly on my A/C system followed by a system evacuation and recharge. Blows cold to 50 degrees fahrenheit. Great thing to have when driving in the Florida heat! - Reinhart
