Nitro didn't want to start this morning. Cranked but sputtered and spit. Would stay running with slight throttle pedal but wouldn't rev or stay running if I let off. The red choke(I presume) light was on. After about 4 tries it fired and ran fine but now check engine light is on. Throwing P606 and P061c codes. Can't find much info on those two codes.I love the truck but geez...always something!
