charles Posted January 8, 2006 Report Posted January 8, 2006 For a 2 months the engine accidently misfired (running on 3 cylinders for some seconds) , but not consequently. The other time it was running smooth.At moist it seemed to be more sever, so I suspected the electrical system.I brought it to the FORD dealer for a diagnoses; they replaced the MAF, all other readings were OK, but my problem was not solved. I checked all wiring for many times, but could not find cracked or corroded contacts. I was at the point of selling the car, but who would buy a trouble car? I still suspected the lamdba (oxigen) sensor, however the Ford Dealer said this sensor was OK.So I disconnected the connector and than found the error.The 4 pin connector was corroded. A bit of contactspraydid the trick. Quote
