Vibration at idle caused by loose engine bolts?
I have noticed over the last couple of days that I feel a little vibration when sitting at stop lights with the clutch in. Almost feels like a miss but I cannot hear any missing or gauge any movement on the tach. Cant feel any vibration at speed or when going around corners. Going to try and check out the mounting bolts tomorrow. Really have noticed it since header install. Related?

I've heard of some engine mount issues. Not sure if that would cause your type of issue though.

All bolts were torqued to spec. None were broke or loose at 24,500 miles.

After asking around I'm chalking the vibration up to the 1-3 header rubbing on a mounting bushing. After I was checking my engine mount bolts I noticed how close it was. Not sure if it can be moved away or not. NBD though. I can live with it.

Unfortunately "vibration" is not enough to pinpoint anything.
