I've had my 2012 Laramie about about 3 months now. I been using the remote start on the key fob. Started it one night, ran for about 15 seconds and shut off before I could get in the truck. Check engine light came on at this point. Had
the code checked and found that the code set was PO14C. Printed out a list of issues that corrected the problem. Most involved replacing the O2 sensor and wiring harness. 2nd most fix involved cleaning the EGR valve. Mileage has dropped considerably. I plan on deleting and adding nd adding a tuner
as soon as I can get with Double R for advice. My question is should i ignore the code until I delete or go ahead and repair. I hate to spend the money to fix if I'm going to deleting soon anyhow.
