Losing Mid-Range Power I've got a K5 with a 5.3L with a TH350 and its losing power after I take off. From a dead start it has plenty of power and will roast the tires but after it gets moving at a cruise speed and you try to accelerate it just bogs down. There are no codes. I've swapped out MAF sensors, O2s, and all the live data looks good on the scanner. I'm just not sure unless it could be a torque converter issue.
