A friend's 92 RXL seems to idle alright (1800-2000) when first started up, but after he goes for a little ride he said the idle will stay way up at like 3500-4000 and the sled will even start moving.

Any thoughts as to what might be causing this? Does the computer have to relearn things like a car (Computer and battery were out for a while)?

I'd be checking throttle body boots for leaks and the crank seals.

boots are brand new and i told him to check the PTO seal (you can't get to the MAG one). Has a little over 6K on it.


Oh, forgot to mention, he said it is also smoking quite a bit too (blue), more than last year, and he even has Shell synthetic in it right now.
