Does this wiring idea sound right?
Turns out that I did not ground my MAP sensor near as I can figure. WOuld explain the poor running. Can I just run the MAP ground to any ground, or does it have to go through the ECM. If it does have to go through the ECM then, can I run a wire from the MAP to a ground, and that wire back to the ECM?
Thanks

I Think it needs to be grounded to through the ECm. I would see if one of the wires from your old MAF goes to the ECm and if it is not being used, wire it accordingly

FYI I just used the wiring diagram for the MAF and used a volt meter to verify, then used the +5v, Grnd, and signal from the MAF and ran them to my MAP. Verfied the pinning on my ECM..and done.
