Hi my name is***** been having an intermittent problem with my 2004 f250 with the 6.0 powerstoke. This problem started back in January, had it happen off and on for a few weeks. Then went away for months. It did it to me again back in may. My batteries needed changed and after I replaced them with me and cleaned the corrosion off the connections, I never had the issue come back. Until today 10/11/16. The issue is, intermittently the engine
will have a low rough idle. It will idle fine at 650rpm then drop to around 450rpm and bounce back and forth like it's going to stall out. It never does stall out. When this is going on the accelerator pedal is unresponsive or just takes a while to respond. Shutting the engine off and then restarting later has been bringing it back to normal operatoration. I first thought was the accelerator pedal sensor is going bad, but I'm not sure if that is the cause or if the a purged factors at work. I change my oil regularly at 3k miles to 4K miles with delvac elite 10w30 semi syn. I was changing my fuel filters with every oil change but last time I changed them was in December of 2015. I plan to change them with my next service in a couple weeks. Your help will be greatly appreciated.
JA: Have you changed a battery before?
Customer: It was the first time in this truck.
JA: Are you fixing your F250 yourself? What have you tried so far?
Customer: I haven't tried anything to fix this issue. My batteries died on back its the end of May, and there was a lot of corrosion on the cable ends, I installed 2 new batteries and cleaned the cable ends. After that I have not had this idle/accelerator pedal issue. It just came back tonight after having no issues in 5monts. It first came about back in January.
JA: Anything else you want the mechanic to know before I connect you?
Customer: No, I believe it's all there. Thank you
