Drove from Northern New Mexico to Los Angeles today in the 4BT Scout, for work.
Pulled over for fuel in Flagstaff. At the bottom of the off-ramp, when engine came down to idle, RPM was bouncing up and down between 700 and 900, on about a 2-second cycle. At the bottom end (700) the whole engine was shaking pretty badly.
Stopped at Home Depot in Barstow and rigged up something to keep idle at about 975-1000. There is no RPM hunting at that high idle, so it's an OK workaround for now, I guess.
Did some poking around over on DieselTruckRegister.com and people over there suggest that it's the governor spring. Sound logical? I had the pump rebuilt only 3750 miles ago by Tennessee Diesel Care and Performance.
If it's the governor spring, is there somewhere I can pick one up in LA?
Any ideas are welcome. I am here in LA for a while and would like to get it sorted out, as I will be using the hell out of the Scout.
Thanks, as always,
