As i have been logging, i am noticing that my IAT1 is always reading over 200°F. IAT2 reads normal (about 10° above ambient) but my IAT1 will get as high as 250°+. Anyone else have this issue???
Well, since IAT1 is located on your MAF, you may want to try cleaning it in case debris is skewing the temp reading. Failing that you might need to replace it.
