[QUOTE="03cobra#694, post: 8453482, member: 75301"] DTC: p2197 Ford says the cause may be an engine vacuum leak, possibly around the PCV valve or in the PCV vacuum plumbing. Such a leak may set the following DTC: P2197. The code may indicate a lean fuel condition or a lack of heated oxygen sensor (HEGO) switching. Ford says not to replace the oxygen sensor, MAF sensor or PCM because the cause may only be a vacuum leak or an incorrect sized PCV valve that flows too much air. I`d look for a vacuum leak [/QUOTE]
