Car has sudden surges of power???

[AcidDrag0n]

Whenever i'm driving around 55-70, if i start to push down on the gas the RPM's go up ~3k then all of the sudden they drop to 1K in an instant. Then if I hold the gas whever it was when the RPM's fell the car has sudden surges of power like I let off the gas, then step back on it. Any Idea's?

Sounds like the tranny may be starting to slip, or the torque converter lockup is kicking in and out. (if you have an automatic that is...)

If I remember right, your car is a '95 or so. In that case, it should be a cable operated throttle, so it wouldn't be anything weird like the pcm opening and closing your throttle on you.

Just a little surge or stumble could be a sensor, but if it's a big surge with the rpms changing a lot, sounds more like tranny to me.
