98 blazer my 4 wheel drive i gotta press the gas way more then normal sometimes... Sometimes it feels fine but sometimes i gotta press te gas alot for it to go... It feels like its not engaging or like the tranny slipping kinda feel and sometimes the car feels like its really heavy like it wants to slow dowb and when u get clOse to a complete stop it will stop...

Is this normal ive never owned a 4wheel drive before all my trucks have been 2 wheel

 

Are you in 4wd when it is acting this way or does it do it in 2wd as well?

Have you checked to make sure that you do not have a brake hanging up?

 

Only in 4wd doesnt do it in 2wd...i feel a really slight grind or slipping type feel at low rpms sometimes not all the time. Feel like a tranny slipping type feel to it cant really describe it.

I just replaced all the brake pads and spun the rotors im sure its not the brakes
