“My 1990 Isuzu Trooper, standard, intensifies its revs in idle suddenly. Sometimes it goes up and down, up and down... And I can see how the temp gauge rises quickly. My momentary solution in such cases is to stop the car and shut off the ignition and wait, sometimes this leaves me some minutes until it starts revving up and down again. No injuries so far, but I have not been using the truck much for this same reason. I would like to know what id the cause so that my mechanic can solve it.”
