Hello all! I am a new member to the forum. The Service Engine Soon light came on the other day on my 07 F250 deisel. I had Advance Auto put a probe on it and it came up with P1335 which according to them meant there was either a engine misfire or something to do with the ignition. Could water in deisel cause this or just a tank of cheap fuel in general? The truck is running fine but don't want to play around with a potential problem either. All tips greatly appreciated. :bowd:

i don't know why thats not working. anyway it says it is a common problem in the diesels. It is a egr valve not functioning properly. They say that it is possible to clean. If the valve is not opening all the way it is not fuctioning properly. I don't know much about cleaning it, maybe just replace it. It sounds as if it is a common problem with the ford diesels.
