Not a SC problem, but the 2.5 duratec in my 98 contour shares the same coil packs as the SC. Got a blinking check engine lite, misfire bad enough to damage converters. Misfire on cyls 1,2,and 3. Replaced the coil pack with one from federated. Ran great for 10-12 days-2 wks. Now the same misfire 1,2,and 3 is back. Dbl plat motorcraft plugs and wires, ford o2 sensors, and full tune up was done in Mar '12, so plugs and wires r less than 15k. Inspected wires, they r good, pulled plugs and they looked fine too. This is a waste spark motor, just like SC's, what could cause one bank only coilpack failure? I thought maybe it was an injector problem, not ignition, but why would changing the pack clear the problem for 2 wks if it was injectors, or harness? Did a full wiggle test had could not get any change. Not showing any other codes, and watching sensors on the scanner, all seem to be functioning and correct (TPS, IAT, ECT, load, Massair%, timing, ect r in the expected ranges and changing as the car warms up, if reved ect).
HELP!!! I don't want to just keep throwing coil packs in and burning them up!
I need this car to be reliable (at least one of my rides has 2 B )
Thanks 4 suggestions or ideas
