I had this also n I changed every thing but one ur later i.found out it was my in put n out put speed seniors. So today I'm driving my Buick rendezvous with no power loss but change both of your seniors because they work together. Run a higher grade gas in ur SUV for a couple of times n u should be fine.

If your ABS light is ON Check all four of your wheel Hub sensors, If one of your hub wires is broke it tells the computer that you don't have no brakes. The computer tells the car not to accelerate.
