in a nut shell, these were CM codes i pulled up. I'm taking the 93 4.0 from michigan to maine and i'd like to ensure this is either not an issue, or gets fixed.

how are the three related? 72 and 76 say left and right lean. are they in fact bad, stuck lean, or is say the MAF off, throwing the fuel mixture out?

i did accidently cycle the key switch while the code reader was hooked up, so could that have thrown the 542, or is there in fact a bad ground?

and...is the 542 causing the lean faults?
