Lately it's been cold in the morning, about 20* and my truck has started throwing the knock sensor code, which it didn't do before getting cold. I've check the wire and I doubt the knock sensor is bad as it's only 2 years old from Toyota but I'll still check. My only other through would be it having something to do with my start up idle at 2k and my regular idle being at 1,500 because I got tired of the the idle of the Engnbldr cam plus when I turned my A/C on it'd go back to 1k rpms.
The only other difference between this winter and last is I'm at a high elevation running 85 octane and not 87 octane.
