something really weird happened to my SVX the other day. generally i know what is going on with the thing, but this kinda freaked me out.

okay, so, i started her up after work one night after a very unexpected snowfall, and like usual the rpms sat kinda high while it warmed up.
and i waited.
the thing got warm but the rpms were still idling at like1600.

wtf?

so i drove off. i had to put it in neutral at the stoplights because the thing really wanted to go.
driving was normal. it would accellerate to about 20 without help, then i could keep it around 2100 at speed limit.

the thing that worries me is, i thought this was a sign of a TC that is about to crap out. the part the confuses me is it wasnt slipping at all. pulling very strongly.

any ideas whats going on?
i have some short video of the tach if you want to see.

I don't think this has _anything_ to do with your transmission.

TPS might also be a good bet if there is nothing mechanical like a lost spring or stuck linkage.

whoops. missed you guys yesterday.
i picked up a hitchiker. woot. made ten bucks.

anyways, no, there was no code, and everything seems to be fine today.

the revs pop up slightly when in neutral, but they are low to begin with.

completely random event.
