Loss of power
I have a 2001 GMC Sierra 2500 diesel it lost power
going down the highway and wouldn't go over 65
mph check engine light came on but now it's
running normal I want to see what can I do to fix
Have the CEL trouble codes read to know what is going on.
Sounds like it may have got some air into the fuel system. Check the fuel filter for leaks and moisture.
