Hi all just replaced motor and tranny. Runs and drives great now but the CEL Came on today very briefly. I checked the codes and all it came back with in koeo was 54 which is the intake air temp sensor. It's a new sensor and has about 50 miles on it. After the CEl came on I did notice that the truck was idling about 100 rpm higher and after doing the koer test it came back with code 12 AND 13 saying engine idle is too low and too high.
I put the old sensor back in and unplugged the battery to reset computer so hopefully that will solve my issue. If it doesn't what should be my next thing to look at?
