Answers :

Okay, when you changed the Number 2 plug, did you also change the wire? Have you checked the Injector seat for a leak? Do this by spraying Choke cleaner on it while engine is running to see affect on RPM.
\012Check for Intake gasket for leaks. Clean the MAF sensor with safe Electric cleaner. If still no help, on some Fords there was a groove under the Airhorn gasket that needed periodic cleaning. Its 8 bolts and a $10 gasket.
\012Put on a pressure gauge at Injector rail and see if fuel pressure drops on acceleration. You can do a cylinder balance test Electronically and see if compression is a problem. Code 302 is a misfire on the #2 cylinder.
\012Would like to know outcome and if this is the DOHC engine with Cam Phasers.
