I have an 07 Equinox that's giving me headaches.
First it was the throttle body/TB sensor. It was removed, cleaned and the sensor replaced. Next, it was plug wires. New ones installed. Now, the
engine is running rough, hesitating, gas mileage has dropped and a strong sulfur/rotten egg smell from the exhaust. The vehicle has 136,000 miles, so
I'm really starting to suspect the catalytic converter. Everything I find on the internet points to that also. It does mention other problems, but
most folks say they replaced the CC and their troubles were over.
