No POWER at low RPM and vibration in overdrive
Couple issues that I wanted to see if anyone had some ideas. I have a 2003 F350 dually with the 6.0L and have been reading on the blog and have a couple of different questions. I had the computer flashed about a year ago and it seemed to help the problem starting when cold and the low power at low RPM, but it has seemed to get worse again. Not sure if my Bully Dog Dyno Dominator caused the problem, but I have recently removed it and wondered if it could have affected the computer and I would need a reflash? Also, anytime I am in overdrive below 65 mph I get a vibration, more noticeable under load or trying to accelerate. I have an ATS transmission and last year had to reinstall a couple bolts from the flywheel to the torque converter. I checked it again and they seem to be tight. Ideas?
