Having problems with your 1998 GMC Jimmy ?

1998 GMC Jimmy losing power when going up hills

\015 It drives fine through out the city but once I get onto the highway or go up a long hill the power bogs down and the check engine light comes on. When this happens I need to shift down and increase the rpm's to get over the hill.\015 Posted / edited by AnonymousUser on : 19-03-2018
