Hi friends,

My 92 740T started misfiring slightly. It only misfires once warm, and only seems to misfire while warm at idle.

3-4 weeks ago we found a spark plug wire boot that was burned and cracked. All of the spark plug wires and boots were replaced. When they were replaced, the misfire disappeared. But this week it returned.

On a seemingly separate note, every once in a while while driving the car will randomly go into overdrive (by which I mean the same effect as if I pushed the little button on the shifter, also it's an automatic). When I try to push the button to turn off the overdrive, it usually doesn't work. I frantically push the button until it turns off ~1min later. From my research, this seems to be an overdrive relay than needs to be re-soldered, correct? Where can that be found?

Any suggestions are greatly appreciated!
