Rough Idle & Pop
Truck started idling real rough about a half block from my house the other night. I limped into the driveway and shut it off. It almost died several times on its own.
I immediately thought it might be a fuel issue. The next day I drained the fuel filter, flushed it for a few seconds then pulled the filter out. Filter was changed less that 400 miles ago and looked to be ok so I put it back in. After the fuel flush the truck runs much better, idles normal but I get an occasional Pop only heard it once or twice and what sounds like some scratching.... Thats as good as I can do to describe it.
