We are now 17 races into the 2012 NASCAR season; that is, 17 races with the new electronic fuel injection for the first time in our sport. We still have not had an actual issue with the fuel injection.
The issues continue to surround the parts and pieces that are tied into it, though.
What happened to Tony Stewart in Saturday night’s race at Kentucky Speedway was, to my knowledge, the first time we had seen that issue. I did a lot of digging and found out it was a sensor on the cam that caused his problems early in the race. These sensors are ones that send information to the brain-box of the EFI system.
