scrming, the first code ever thrown was due to engine temp sensor. First cold weather snap, I get a code that says the AC is off due to engine temp. Stays on for two days, goes away, no history of the code in the computer. This is after IAT relocation, which was done in warm weather.
Second code is after header install. Cold weather and a couple, total of 5, 1/4 mile passes. Two of those passes made in 20* weather.
I'm begining to wonder if maybe an o2 sensor wasn't plugged in right. Fuel mileage has gone down though, so it's definitely rich, or bad gas.
I did the fuse pull by pulling out 5, then 20 and putting them back in in the same order. Isn't that correct?
