Jacked around with the uglytruck last night trying to diagnose my stumble. Stumbles when accelarating from idle. Unplugged the TPS and it immediately idled up. Like 500 rpm. Adjusted the idle back down, hit the gas a few times and it seems the stumble has gone away. Figured it had to be the TPS but ran the diagnostics on it anyway. Everything seems to check out. Have seen several posts on other forums with people saying that they had a bad TPS and just left it unplugged without any problem. Does this sound right?
