Code 22 Blues
Thanks for all replies to MPG Problem, takes 1-5, guys. Still getting really crappy mileage and KOEO self-test still sets a code 22. Have replaced air bypass valve, MAP sensor and tested MAP sensor in all ways manuals describe (it passes all tests). On advice from tech at www.westecauto.com/HyperBBS/FordForum/?ListType=Reversed, I even scrounged up 4 MAP sensor plug/connectors in 2 wrecking yards and wired these in one at a time to test the connector. Still get a code 22, which this tech tells me is why the truck is running rich and sucking gas. Very frustrating!!!!! Anyone else had similar experience with code 22 and MAP sensor? What was the fix?

First, de-carbon the vacuum line all the way back and into the intake,or just run a new heavy wall hose to it. Next, put a new ECTS( coolant temp sensor). It too plays a big part in the fuel mixture ratio.
