Contour Enthusiasts Group Archives Forums General Troubleshooting Codes

Alright, heres my situation. When I bought my v6 Contour MTX the Check Engine light was on. I took it to my mechanic and I was told that my precats were clogged. I purchased Mil Eliminators to shut off the check engine light and it stayed off for about a day. Now it came back on and is throwing codes PO133 and PO171. Does anybody know how I can get this problem resovled!?! I need to sell my car and so I need to fix it and get the Check Engine light off. I installed the Mils just like the directions said... and I sodered the wires, ect. The PO171 code I believe is entirely unrelated. The PO133 I believe is bank 1 o2 sensor problems.

Thanks for your help!
