Hello Im new here and Im having a problem with my 1999 blazer 4x4. I feel that the car slows down quick when Im driving on the highway, like if Im doing 70 mphthen I take my foot of the gas pedel the car slows down quick. I dont know what causes this!!

For the vibration I've recently changed my shocks still everytime I hit a bump it vibrate real hard.

Thanks

 

Have your brakes checked, possible one or more is hanging up. Korey.

 

Thanks I've recently changed my front rotors and brake pads didnt really check my rear!!
Freidns told me thatit could be thetransmission not shifting to the 4th, but I highly doubt if it's the transmission, because i can feel it shifting normally. any other ideas??

 

You say you replaced your front brakes...how were they, were they worn more on one side that the other? If they were then a caliper might be sticking.
Check that the parking brake cable is working properly and not holding the rear brakes on.

 

Ok I'll check them asap. Thanks
