SHake and shudder/max rev and rough idle with a 2007 cummins isx.

OK. I pulled into a toll plaza, paid then as I pulled out, the engine RPM pegged and for awhile wouldn't come down. Shut the engine off and restarted, running rough and when I push the clutch in it revs back up. Rough idle between 800-1000 rpms. I changed all the filters about 5 hours ago, then got fuel. Rode 4 hours and this was the first time I actually slowed down to go through the toll plaza. 2007 Cummins ISX. Any ideas? I have a service guy bringing new fuel filters but not sure that is the answer.

 

No warning lights. I was thinking about the fuel. I also got fuel for the reefer and its running fine.

 

I tried tightening them again. I have a truck bringing new filters out. I've been sitting for about 45 minutes. Tried starting it again. still rough idle and some shuddering between 800-1000 rpm's. Pushed the clutch in and it revved to about 13-1400 rpm and stayed there. Not revving to the governor anymore. Still seems weird that all I have to do is lay my foot on the clutch pedal and let it drop to where the play stops and it revs up. The place where I got the filters changed, fooled around under the truck for awhile They had an issue with the oil filter housing. Is there anything underneath there they could have dorked up?

 

So when the service truck pulled in he looked the engine over and said the filters won't help. Something is broke in the engine. He suggested a good shop. I started the truck, still shuddering but I the rpm's were not revving to the governor, I started nursing the truck to the shop, it cleared out and seems to be running fine. Maybe an injector? Plus a little praying didn't hurt!!

 

OK. I'll check them as soon as I get home.
