Scuze my Egnertz, but, I have a problem with some of the answers on this thread. Can the new types of plugs & coils on these modern vehicles actually "heal" themselves, albeit temporally?
If I'm reading correctly, at certain speeds, all kinds of shake, rattle,& roll begins, speedup, things return to normal.....for awhile.
And the culprit(s) are the plugs/coils or both?
Regarding coil test. Are U sure there's not a test? My old 97 Plymouth Grand Voyager 3.3 has 3 coils, one for every 2 cylinders. There is a simple ohms test one can do on these coils to see if there any good.
