CEL Light
Just completed the decarbon process as described in this link:
https://www.ford-trucks.com/forums/showthread.php?t=100739&highlight=pinging+
The CEL came on 5-10 times during the 3 mile @3,500 RPM drives. Should I disconnect battery and clear for next code scan? CEL light has NOT come on again since decarbon process completed. The knocking/pinging has not gone away so next step is to check and clean the MAF. Biggest knock is immediately upon starting engine.
