Check your exhaust system. Is your catalytic converter plugged? That could cause those symptoms as well.

Had a similar problem before. Even the fenders got hot The whole problem was the spark plug wires were crossed. On mine the 4 plug was connected to the 8 and vice versa. Make sure they are connected right.
