97 7.3 power loss, rough idle
Hi all! Amazing site here! My 97 F350 is idling with a slight surge, and seem to have some power loss. When I give it fuel in neutral (2000 rpms or so) and let off it either dies or barely recovers back to an idle. I had the lift pump(fuel) replaced a week ago and a week before the cam sensor was replaced. Ran the codes and nothing. I did today however check my exhaust backpressure tube, it was clogged. Cleaned it, and still have the same problem. My ehaust back pressure is reading 17 psi at 2000 rpm. I am at a loss. I also pulled the plug on the icp sensor while engine was running to see if it would kick into failsafe mode and help, but made no difference.
