Always nice when the OP takes the time, to post the end result!
This and other car forum threads, often with days or contributions, end with toe OP NOT posting the outcome. Depriving all who read it with a possible learning experience.
Even if it's "I gave up and traded the car in on a Toyota" post the results. Thank you.

Hopefully others will see this post and do some testing before spending the money on a MAF. I kind of understand with the relays since they are so cheap, but still like to see some trouble shooting first.
