Thanks for the tip regarding the potentiometer. I wouldn't be surprised if that's slowly giving up the ghost on my car as well.
I'm definitely also planning to check the DME and open it up to verify that it's got the correct chip in it. My main annoyance right now is that I can't see what the ECU is seeing, which makes it hard for me to validate some of the theories I have. I suspect that aftermarket engine management might still be in the car's future.
If I do keep the existing MAF conversion I'll still have to figure a way to move the air filter to a place where it has a better chance of getting cooler air.
