Question about 1999 Ford Crown Victoria
New plugs motr crft 1 new coil pack reset light came back on help!
1999 Crown Vic is coil on plug. There are no plug wires. Need to run a diagnostic scan to find which cylinder is mis-firing. When you running diagnostic scan the cylinder mis-fire will be represented by a letter not a number if i am remembering correctly. I have a 1999 but its been years since i had any mis-fire. In order to try a more detailed sollution I would need to know more than you swapped a coil pack and changed plugs.

for these codes.
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
