Just wonderin' if anyone has seen ignition coil packs for the 3.5 go a little funky at times. My 'Corde has a random twitch at idle and under load at highway speed, not hard enough to be considered a full miss, but I noticed my lights flicker slightly whenever it happens. I'm trying to chase down the problem myself before I bring it in to the dealer. So far my only two ideas are a bad coil pack or maybe a flaky voltage regulator. It gets worse when the car is warmed up, and if I shut the engine off the power is perfectly fine. Anyone seen this before?
