Freightliner won't go over 45mpg
My 01 freightliner car carrier with a cat
engine will not go over 45 mph. All gauges
and fluids are ok. Everything seems normal
except that it just will not go above 45 and
even slower in the hills. Engine sounds
good and Rpms are normal also. What
could cause this to happen?
Sounds like a governor like a rental truck would have .
Is the turbo working?
