""CLEANING FORD MAF SENSORSFor some reason, Ford vehicles have had a history of MAF sensor problems caused by contamination. In some cases, dirt gets past a leaky air filter and fouls the sensor wire. In other cases, carbon varnish builds up on the sensor from fuel vapors backing up through the intake manifold. Either way, contamination makes the MAF sensor sluggish, and often sets a P0171 or P0174 lean code.The fix is to clean the sensor element with aerosol electronics cleaner (CRC makes a good product for this). The MAF sensor is located inside the air filter housing on some applications (Windstar, for example) or between the air filter and throttle body. Spray the sensor element with electronics cleaner, let it soak for about 10 minutes, then repeat. DO NOT use any other type of cleaner as this may damage the sensor. Also, DO NOT touch, scrub or attempt to physically clean the sensor element as this too can ruin the sensor.""
Volkemon,I got a P0191 code on my trip up to Canada. It’s a fuel pressure related code. Engine ran fine and fuel mileage was great. I cleared the code with my Scanguage. It seemed the code happened after restarting the engine. When I cleared the code the check engine light stayed off until I restarted the engine and after refueling. I replaced the fuel pump module last fall when I couldn’t get the engine started at all and that solved that problem. Any ideas what’s causing it? Could it be as simple as needing a new gas cap?
I bought some sea foam has anyone tried that for cleaning the injection system would that be something to try?
