What ever it is, it does it for a short time then totally clears up.
Makes me think one of the two, the ones on the throttle itself.
Would the Idle Control Unit make it so as you give it some throttle input it has the ability to give a lower perceived throttle, fluctuate (surge) then opps my bad go back to normal ?
Or the Throttle Position Sensor simply malfunctioning for a bit then goes back to normal ?
After that its fine. Shut it off and it may or may not do it again.

I actually thought the trans may be slipping till this last time, and had the throttle opened up a good bit and when it cleared up jumped and took off as I had the pedal down more than normal. No slipping, thats throttle related.. hmmm

So now I'm asking the Montero Gods of Knowledge... is it my rear taillight bulb is out or one of the 2 mentioned culprits ? Haha
