Ok guys, little help if you can. Truck has been intermittently missin from time to time. Well she finally decided to run really rough and give me a 480 and a 2146. Not messin with it till am but pullin the edg/juice off. Its an old version edge juice. I don't think its injectors bit who knows right now. Any other input would be greatly appreciated.

 

The 480 is for the fan clutch. Check the wires to make sure they are not cut. The clutch itself could be bad.

The P2146, Fuel Injector Group 1 Supply Voltage Circuit, could be the cause of the rough running. Might check the wires going to the injectors. Could be damaged where they go through the valve cover gasket.

 

Thanks papaduck. Ohmed injectors and #1 was the culprit. Changed it with a $300 reman , about 1 1/2hrsof my time and she's as good as new. Other than typical wear items, I couldn't ask fpr a better truck. At 269k, Other than this injector, this truck has yet to let me down.
