Left Dallas on my twice a week run up to Colorado Springs. And at about 400 or so miles into my trip CEL comes on. I didn't immediately stop to check out what it was, but eventually did stop and hooked up Insite, it was an 1145 code. I cleared the code just to see if it would come back. I left Insite hooked up for the last 100 or so miles for the day. The CEL did come back, same code, but before I stopped for the night it went inactive. Fuel rail pressures were good.

Being in the middle of SE Colorado there wasn't a whole lot I could do about it and the fact is that the truck was running fine, no missing, no nothing. No MPG reduction. No loss of power. I cleared the code again and packed up my computer.

Got up the next morning, went on about my business. CEL back on again. I didn't even bother with Insite at this point. I made my delivery, put another 830 miles on it back home, CEL still on, same code. There are no other codes at all, just the 1145.

Anyone with any thoughts or ideas about this, or is it just a "replace the injector" and move on?
