So, you've got a high voltage fault - engine temp. A low voltage fault - MAF.
And a "trans not in park or neutral during test" fault.
I'm thinking bad ground, or the PCM is toast (reference voltage is to low or is wandering around)
I'd have a look at the connection at the PCM first. Give it a good look and cleaning.
Really soggy up there in the great north west, may be corroded.
Random, unrelated codes often mean - Bad PCM
I will check the PCM at lunch, I'll clean and inspect it before the drive home and chime back in with my results.
Funny thing happened, on my drive into work this morning it ran like crap right up until the last 10 min or so. During that time if I was on partial throttle it responded as it should, anything more than that and it was horrible.
