[dalbert73]

Hello. can Someone help. I have a 2001 GMC Jimmy 4X4 over 110000 miles. It seems to be a conflict in power versus accellaration .. what are some points that I could look at as far as power loss is concern. This vehicle makes sounds as if I am going 80mph and I am only at 35mph and rpm is a only 2???? Thanks Sincerely Dalron SomewhatFrustrated!!!

PS. I had transmission checked>>. OK OK
