Other Category problem
2003 Chevy Tahoe V8 Four Wheel Drive Automatic 113000 miles
I have changed the 4 oxygen sensor, the fuel filter, the 8 sparkplugs and wires and the PCV and run 2 cans of sea foam for the injectors, new air filter, and oil change and cleaned the MAF but still get the error codes. I also donated $10 to 2CarPro. What should I try next. The car runs great accelerating and cruising but Idle is cycle rough idle with the P0171 and P0174 OBC codes and the check engine light on. I cannot pass emissions. What should I try next. Thanks
have the same problem?
