that happens when you clean a MAF with carb cleaner. give it a couple days, that high idle will go away.

trans mount could be bad, or the bolts on the shifter could be loose.

The tranny mount looks brand new, and the bolts on the shortshifter are tight.

does anything else shake, or is it just the shifter?

car shakes alittle, but figured its cause my exhaust is dumped and there poorly mounting, so the muffs move around easily.

Its the drive line I had the same problem. Replacing the u joints helped a little but in the end I replaced the driveline with another and the shake/vibration was gone
