Mine started doing this out of the blue about a year ago.

I never shift out of drive.. sometimes it just slowly drops from 1000 to ~700RPM, and other times I'm already accelerating (short traffic light or stop sign) before anything fixes itself.

My mechanic told me to check and lubricate the linkage. Which I've done numerous times (with ATF). Doesn't seem to help.

One thing I've heard (but not yet investigated) on my car, is that bad motor mounts can cause this. The engine can shift itself (due to the bad mounts) which will put strain on the linkage and cause the engine to idle high.

Has anyone had this problem even though they have relatively new motor mounts installed? That would narrow down if the motor mounts are related!

I run Diesel Purge once a year, lubricate the linkage 3-4 times a year, and have been doing so for the last 4 years. For some reason, this problem just "appeared" one day about a year ago.. not sure what caused it!
