A little background:
I have had this problem pretty much since I bought the car (4 years now). When the car is at normal operating temperature and at idle, the RPM’s will “dip” when I load the electrical system. So, turn on headlights, defogger and hit the brakes and down it goes and the car starts to shake.
So people said to check the grounds so I did. Re-ran them from Batt to chasis to block ect but no change.
So FCM suggested I remove my crappy alarm system with the connectors that are cheap and can cause problems, so I removed it completely, made sure all wires were connected properly…No change.
So with the car idling I removed one fuse after another and the only one that had any effect was the Sunroof/Radio/Interior Light fuse. It didn’t completely fix the problem but the rpm’s did rise back up a a hundred or so. Could be that it is a problem area, could be that it is just responsible for a fair bit of load and makes the difference.
Anyone have any advice here? I really have no idea what to do/try next. It sucks because the car runs perfectly otherwise and I just cant stand this dipping and shaking.
