For the past month, when I roll to a stop sign or street light, when I press on the brakes very hard the truck will shudder (shake, loose RPM's or idle) basically it feels like a little earthquake inside of the truck and it will almost die. The truck idles fine when it is at a stop and seems to be functioning quite well. A couple weeks ago I drove down to Denver from Boulder, once I got there I loaded up a new bike into the bike (took about 20 minutes) when I went to start it to drive it back the truck would not start it just kept turning over and over. Finally I was able to get the truck to start and carefully made it back home. I have not had this problem since although the shuddering problem still exists and seems to be worse in the morning and then not to apparent in the evening after it has been driven all day. When the truck would not start in Denver, one of the generator lights came on (truck has two generators) and then shut off after the truck started running again but I thought that was odd and could potentially be the reason for this problem. I have been told it could be a number of things but I need someone (local) to help me get this back up and running.
HELP!!!!!
