Engine/Transmission (1994 - 1998) increasing rpm on it's own

[TRCM]

I adjusted the idle speed tonight to get it back to where it should be. I only raised it roughly 50 rpm (sped is 780 rpm).



When I went to drive it, when you pushed the clutch in to shift gears, the engine would climb by itself. not real fast, but I turned the engine off @ 3000 rpm.



It did this 3 or 4 times before I could get back to the house.



I couldn't see anything that would be affecting the throttle linkage in any way. So I adjusted the rpm back down to 730 or so, and now it doesn't seem to be doing it again.



Any ideas as to what happened ?

No one on here has any ideas ??

I know this seems like a simple question, but how exactly did you adjust the idle?

adjusted the high idle maybe?

I've seen this also in my 2001 ETH the RPM's raise to the max till I can't handle it anymore.

I turned the low idle speed adjustment screw/bolt about 1/2 turn. It is the vertical one to the rear of the lever... the high idle screw/bolt is horizontal and up front & top of the lever.

Sounds like you got the right one. I would check the adjustment on the gov. springs.
