probably the tps or throttle position sensor handin' out bogus instructions to your computer. think these things are contact operation, not magnetic field operation, so could possibly be worn, and tryin' it's best!

Thanks I'll try that my speedodometer is not right, i put a sencesor but its off could that effect it to?

yes. what you been doin to it, voyages thru the utah desert? must be kinda high mileage? Is it still the ole' cable speedometer (recently found out they don't do it that way anymore) 1991 ~~could be either way- yes, whenever human meets machine, there will be trouble....sounds like a damned GURU already...keep us posted~

It could also be a burnt overdrive band in the transmission or your torque convertor, going out. Have a mechanic or transmission mechanic diagnose it for you.
