Last June I had a new OEM muffler installed professionally. After driving for 45 mins the car almost caught on fire. The muffler got so hot that it radiated to the floor above it and melted a 1ft area of my carpet and filled the car with smoke. At the same time my Harmonic pulley broke and the belt came off. I've replaced the pulley, re-installed the belt, and also found one sparkplug wire not touching so I pushed it on. But now within 10 mins of driving the muffler gets red hot still! Am I running rich/lean? Pls help!
