I have a 99 dakota 4x4 when I'm driving at 65 mph the tachometer is turning about 1900 rpms every little while it jumps about 200 rpms then settles back to 1900 rpms. sometimes it does this every couple of seconds then it might not do it for 10 miles. It does it when on cruise and also when the cruise is off. could it be a bad transmission or maybe a bad sensor help! this has been going on for 5 months but now seems to be getting worse.

I had this same problem and did two things to fix it. Unfortunately I do not know which fix was the one. I replaced the rear wheel speed sensor located at the top of the rear differential ($40) and I put a pad on my brake pedal arm to depress the brake light switch 1/8" further in

I had a similar problem of intermittent high rpm's (and noticable loss of power) at highway speed. The Truck is a 98 Dakota 4x4.
I replaced the throttle position sensor, with no change in performance. I had the tranny checked by a trusted (friend) mechanic - again no problems. The problem was that the catalytic converter had failed. At highway speed, the broken bits and pieces would choke off the exhaust causing high rpm's and loss of power. But at low speeds everything is fine. It 'feels' like a slipping tranny, but is not. I replaced the catalytic converter for about $500 (CAN) and everything is back to normal.

You can test your TPS sensor (to an extent) with a digital voltmeter. Connect the positive lead (back probe) to the center connector, then the negative to a ground. Turn the key on (do not start the truck just turn the ignition on!) now watch the voltmeter as you slowly open the throttle by hand.
It should smoothly increase to about 4.0 volts at wide open throttle (.76 or so at idle, it can be lower but .7 is optimal) if you notice a dead spot or a place where it jumps around, replace your TPS sensor. Just remove the 2 torx T-25 screws and note the way it was installed. You must "preload" the TPS by putting it about 1/16 of a turn off of alignment then turn it (you should feel slight resistance) this is to ensure that the TPS is on the flat blade like end of the throttle blade shaft completely...
Then reset your computer, start the truck and do not toutch the gas... let it idle for about 1 miniute (to let the computer learn the new inital tps voltage) then shut it down and do the same again... thats it
Hope I helped
