when the car is cranked up and idles... the rpm's go from 1000 to 2000 back and forth back and forth.
i turn off the car and unplug the tps and the rpm's stay high.
with the tps unplugged and the rpm's staying high, i believe the tps works fine since it is trying to bring the throttle back down to acceptable norms.
i unplug the map sensor and it idles lower than normal, but at least it is idling.
i swapped the map sensor a few minutes ago... then connected the battery and cranked it up... idled constant at 1200 rpm... after a few minutes i revved it up a little to get it to drop to normal rpm and then it started revving up and down again.
what the hell is going on?
anyone have any ideas?
