ok so I am going to make this short... I have been experiencing power loss while accelerating over the past few weeks. I noticed it when accelerating onto the freeway. It feels like im letting off the throttle even though I am obviously not. it will usually do this for a few seconds and sometimes the power comes in and out then finally starts acting normal and accelerates like a raped ape. No CEL or codes in ECM. I figured I had a plugged fuel filter. Just got back from a 2500mile trip and figured I may have picked up a bad batch of fuel. I just changed the filter last night. After I changed it I went out and drove it and it ran fine so I figured all was good. Then today I was driving around. I have maybe 50 miles on the new fuel filter and it started acting up after a 15 mile drive at ~ 70MPH and when I start accelerating from a red light it starts acting like I am bouncing the throttle then starts taking off after a few seconds. I am stuck. I have read about the turbo vane position sensor, but I am not getting any codes whatsoever. I cant seem to duplicate the issue now, but I have my edge insight set to show turbo boost and fuel pressure so when it starts acting up I can at least keep an eye on those. If you have any insight, it would be greatly appreciated. I had the trailer on last weekend and it started acting up trying get on the freeway (not a good feeling). Thanks guys..
