I have a 2008 gmc yukon denali.

The rpm needle jumps & I don't have the takeoff power as usual but after I'm at 60/70mph, it runs smooth but the staggering/sputtering/trembling feeling begins after I reduce speed.

I just cleaned the throttle body, my trans fluid is full, although it appears to be a small leak in one of the hoses that connects to the radiator.

I'd appreciate any good advice to repair this issue. also, the stabilitrak/engine light flashes & stating that traction control off...🤔
