Q: Bogged down sound on 2004 Chevrolet Trailblazer

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
My TB makes a bogging down sound when I accelerate from complete stops. It goes away at about 20-30 mph, and it seems like its using more fuel. Some ppl say this could be the Transfer Case going out. Any suggestions?

No the Service Engine Light has never came on, but my ABS light is on because I'm having problems with my front hub assembly.

Is your Service Engine Soon Light on? It this just a sound you hear or is the engine really bogging down?
First, try using a can of Seafoam in the tank to clean out the fuel system. If this doesn't work, try changing the fuel filter, next step would be to have the catalytic converter checked, still nothing? Have the fuel injectors checked, and if that doesn't work...take it to Porsche for a diagnostic.
