Over a long hill I loose power. Does not smoke, runs good....runs fine on level ground....but hills. just does not have the power that I think a 5.9l gas should have. Any suggestions?
I had the same problem. I replaced the intake gasket and it works great.
Have you checked your catalytic converter? I had this problem with my '96 2500 5.9l on long hills and it was really sluggish on steep hills. I thought it might be the transmission not down shifting but it turned out to be the catalytic converter was clogged.
