    Hey y'all I have a 2000 3.8 and just recently I started getting like 80 miles to a full tank, have no acceleration power for like 30 mins with pedal to floor and then all of sudden gains power outta nowhere, and then my headers and whole exhaust system starts glowing and my car fils up with smoke coming from the back seat. Also somehow had blue flames with white tips coming out of flowmaster muffler during open throttle. Tranny has been getting super hot too, with slipping, along with spark plug wires keep partially melting and it gets too hot under the hood to open after idling. So far I have replaced spark plugs, plug wires 2x, pcv valve, iac gasket, upper intake gaskets, belt, camshaft sensor, fuel filter, injectors, coolant temp sensor, transmission fluid and filter, Checked the cats and muffler, cleaned the throttle body, egr valve, iac valve, air intake, air intake, air filter, checked for vacuum leak, checked timing, maf sensor, and Ive used tons of lucas injector cleaner. The only thing I haven't really done is leave the negative battery connector disconnected for 15 mins or so to reset it. But could that really cause all of the problems with the headers and exhaust system? I unplugged the o2 sensor before the cat and it quit glowing for maybe 2 days then started glowing again. Then disconnected the muffler and it quit glowing again. The timing was a little retarded until replacing the camshaft sensor. The timing is back to normal but still having glowing headers/exhaust system and plug wires melting problem along with horrible gas milage. This car has already caught fire 2x. I cant go anywhere BC of it catching fire. Can somebody please help me before I blow this bitch up on purpose?

    You may want to check to see if your camshaft synchronizer is installed correctly. I have heard that if installed in the wrong position that it can cause your symptoms. Its what your camshaft position sensor bolts to.

    Yeah I actually had to move it like manually with my hands instead of the magnet moving it BC it doesn't want to catch on the magnet. That's really how I was able to adjust the timing and get it half Ass back to normal

    Red hot exhausts means you have raw gas getting past the combustion process and dumping raw gas into the headers and downstream. Usually destroys the cats as well. You may have some stuck open injectors. For cleaning them, contact the Injector Man in Fla.

    My daughters car had the same thing and its like six shooter said about the gas. I was driving my daughters car and it nearly caught on fire. The cats heat up real bad when this happens. Red hot!
