Hey, I'm relatively new here and would like some suggestions about my wife's Contour. It is a '95 with 180,000 miles. It lost power and was running really rough one day. I pulled the codes and got a 181 KOEO, and a 326 KOER. I had a really hard time starting the car for the test, so I checked the plugs. one was improperly gapped and carbon fouled, (not my work;we had the head gasket, water pump, timing belt, etc. replaced by a shop). I regapped them all and cleaned the one that was bad. The car cranked easily and drove well on the test drive. The next day, my wife tells me that it is running rough again. It is an intermittent problem, but the car sort of "bucks" every now and them. It is especially bad when going uphill, and when starting out in first. I looked back to the codes, and got several different definitions fro them depending on where I searched. Frustrated, I took it to the Pep Boys chain. Well, all on this board are probably familiar with the noisy cam followers on these cars. Pep Boys heard that noise and thought it was a warped cam. If it was a warped cam, wouldn't the car run poorly all of the time? Based on all of this information, where should I start?
