I recently have noticed a more severe decline in power with my Tahoe. The problem has been occurring for quite awhile, but nothing major has happened. Now, I'm beginning to have issues such as the transmission hesitates to shift at WOT, and won't go above some speeds. This doesn't happen all the time however, and when I tested the TPS I got a smooth voltage reading from .6v to 4.5v. It has 50,000 miles on the new engine, transmission hasn't been replaced, and the vehicle has total 199,500 miles on it. The O2 sensor, MAP sensor, Temp sensors are all new. Everything else I can find suggests the TPS, but when I tested it, it worked fine. I just don't want to drop $40 on a sensor I don't need. Anyone got anything else I could try?
