Driving down the road in 1999 chevy tahoe pulling a trailer, the truck loses power. Advice? Cadalitic converter and fuel pump were just replaced. Also, the car will turn on, but wont accelerate.

    I’m having the same issue. I have an 2004 Tahoe. Seems like soon as engine gets warm that’s it. Starts acting like catalytic converter is plugged. Can even put hand over tail pipe. I’ve replaced fuel filter air filter mass air flow censor. Went to have catalytic converters replaced today and mechanic says he hooked it up to computer. Code u-1000 came up. He says it’s a bad ground to computer. I’m taking it to different shop Monday to have them look at it.
