Hi. I have a 2006 dodge durango (170K Km) that is stalling when travelling slow. It is showing the following codes: P0456 PO406 P0138 P0141 and P0420. I have replaced the Catalytic Convertors and O2 sensors. Codes are still coming up. What to do now?
Did you replace the O2 sensors and catalytic converter with OEM or aftermarket part? I presume also you replaced those after you got those codes?
Also, did you go through some of the troubleshooting steps listed at the following links for each of those codes:
