Will do, but it's only been 3 days since i first started it, so "long ago" is a bit of a stretch!

Thanks,

Lol, I know, thought about that while writing. Long ago in thread terms, like a lotta posts ago. I realize in time it hasn't been long but this is the interweb where time doesn't actually exist.

Re: eRod runs better without the MAF

Found and connected the third ground (whooops!) but predictably it made no difference in the MAF situation, unfortunately. Will advise when I get the new replacement MAF.

Battery reset everything, it may not go away immediately. Needs to cycle enough counts.

Did that a number of times because the battery was out of it daily for a while to make room to work.

I reset it with HPTuners, cleared all codes twice. Nothing magical about a battery reset that a DTC reset won't do (except clear long and short term fuel trims) so pretty sure no amount of resetting will help at this point.

Re: eRod runs better without the MAF

I purchased and installed a new MAF, same problem, no difference.

About the last thing I can think of would be to figure out the pinouts on each of the MAF connector pins back to the ECM and check continuity. Anyone have any other ideas?
