Engine has low rpm miss, skip or shudder
2003 7.3 L has a miss, skip or shudder from about 1200 rpms to 1500 rpms. To make the shutter go away I just step on the throttle a little more and the skip goes away. When I mash the skinny pedal the truck takes off without a problem. The engine starts up quicly even in the cold weather. The truck idles smoothly and makes plenty of power up top and generally runs well except for this.
The skip is more noticible with the higher HP settings on my TW Chip (extreme). My MODS are in my signature. I don't notice any miss at highway speeds (55mph and up). There is no SES light. I checked the oil rails to make sure they were full of oil and I drove the truck with the ICP sensor disconnected and it didn't make a difference. I'm hearing a louder than normal clackity, clack from the drivers side valve cover. I'm thinking maybe an injector is going bad. Any help would be apreciated.
