Not sure where to put this so i will start here. I have a motor and trans out of a 97 sst ram. It is still fuel injected. I have developed a miss but only after it shifts into overdrive. It will miss when i lighty ste on the gas. If i put my foot into it it runs fine. I have replaced plugs, wires, throttle position sensor, fuel injectors. Only codes i get are miss fire in almost every cylinder and battery temp sensor which isnt hooked up. I have an aermotive regulator that is set for 51 psi at idle and holds steady as i increase throttle. What am i missing?
