OK...I returned the Auotlite out back in the Motorcrafts.

I noticed that the OEM Motorcrafts are two different ones.

Plugs 1 & 2 are Motorcraft part # AZFS32F and 3 & 4 are part # AZFS32FE.

They told me that's why the Autolites didn't work and gave me bad gas mileage. That I have to resinstall the OEM's with the two different part #'s.
