I have a 2002 Pontiac Grand Am 6cyl
My car started loosing power when accelerating. I mash on the gas and the car takes off really slow. On the highway I have a really hard time getting over 50mph. The CEL came on and when I took it to Autozone they told me the upstream O2 sensor was showing a fault. I checked the O2 sensor and I saw that the wiring had fallen onto the exhaust manifold and the connector started melting and burning. I have a new O2 sensor ready to be put on but I just want to make sure this will solve the problem before I keep throwing money at it. Someone mentioned to me that the catalytic converter might be clogged but I get no fowl smell from the tailpipe and the exhaust seems to be coming out consistently. Any ideas?
