Engine Performance problem
2005 Questions for all other cars 6 cyl Two Wheel Drive Manual 50000 miles
We have a 2005 Freightliner M2 Class. Diesel. When going 70 mph (after already warmed up), is it normal for the pressure to drop below 50 psi? It is also causing the truck (we believe) to drop speed and not be able to get back up past 65-70.
have the same problem?
