July 18, 201097 Tahoe 5.7 runs great until it comes to pass. Floor the gas Rpm`s go up to around 4000
but won`t hit passing gear until I let off a little. Acceleration is not real good when I do this. I thought it my be the tranny but that was rebuilt @ 179000 now has 187000. So when I got home I put in N maxed the a/c and stomped it. The motor died started right back up. I tried the same thing when it was cold. It rev`ed great (warms up before I can get to a good rd. then same problem). No cel, repalced temp sensor, did tps sweep test, complete tune-up, and fuel filter.
