So while I Drive by RPM's jump up and down and my temperature gauge shoots to high. I have replaced the transmission, neutral safety switch, distributor, spark plugs and spark plug wires, battery, I have checked the alternator and that is good along with the amps, I have check the throttle positioning sensor and I was reading the correct voltage output and the ohms. Sometimes it is intermittent went I Drive so I don't know what is causing the issue. If anyone has any insight as the what I should look for my me know and the comment section below please!
