Engine Performance problem
2002 Ford F250 V8 Automatic 180, 00 miles
My truck has been chugging and lack of power. The are no code showing. The exhaust has a different sound or tone from normal, like an echo. I was wondering if the problem could be linked to a plugged exhaust or catalytic converter. There is a different smell coming from the rear, exhaust area. I don't know if that is related to the problem or not.
