Update:
So after ~50 miles, it still runs fine, but here is what I'm still dealing with
DTC Codes
12 - IDLE RPM High
23 - TPS voltage out of range (new TPS)
26 - MAF out of range
41 - System Lean
77 - System did not receive "goose" test

I marked the 10 deg BTDC line on the harmonic balancer and checked timing with a light.. While running in neutral (manual transmission), timing appears to be 40 deg BTDC.... yet it runs FINE!

again... I'm completely confused.. I tested the voltage on the MAF sensor, and it reads voltage that changes with air passing over it.. Anyone have any thoughts or ideas?

Anyone actually using this forum?
