Hello everybody, i would love to introduce myself but i have this problem with my wifes tj i need help with. I was replacing the gaskets (head and exhaust), water pump, thermostat, radiator and hoses. So i took everything apart and after putting everything back together i procede to turn it on and doesnt sound the same anymore. It idles high and when i drove it around the block it takes of without having to press the gas. I did the battery reset thing and after it turns on normal but once it warms up it does the same high idling and accelerating on its own. I recorded the sound it makes from the exhaust but it doesnt let me upload it. It sounds like a repetitive flapping noise. If anybody has solved this problem please let me know i need to get my wife back on the road.
