A couple of questions. Penny is being a little quirky lately. When stopped in drive with the foot on the brake, the voltage will drop a bit, the car will shudder, the RPM's drop to about 500 and the lights dim. This only happens when the engine is up to operating temperature and ALL of what I mentioned happens in about the span of 2 seconds. I wrote this off as normal since a friend's Bonneville also does this sometimes, but his is VERY rare compared to mine. Penny does this between 2-4 times at every stop light. Tonight, however, it was weird because I came to a stop light which I know is a long one, so I put her in neutral and went to look for a CD. Then, the voltage dropped to below 14, the lights all dimmed, and it would only return if I gave her some gas and then it would drop again. However, upon driving for 5 more minutes, the issue did not repeat. Any ideas from you guys? I've been told elsewhere that 3800's do not like Taylor spark plug wires. I've been told that they could be causing this. Any help is appreciated. Thank you.
*EDIT* I recently installed a ZZP voltage booster and it didn't help nor cure the problem. It changed nothing. But I have since removed it just in case.
