MAP sensor

[capnzee]

My 225 Opti max will not idle correctly under 1000 RPMs and stalls frequently. At above 1000 RPMs it seems to run normal. I changed plugs, no help. Dealer checked and gets a MAP sensor "bad" light. I know nothing about these new computer driven monsters and we plan on installing a new sensor. Also got a throttle body sensor light once but then it went away. The cam on the throttle spark mechanism seems worn????? Any hints? Wish I had my max's with carbs back.

Replace map sensor first should correct your problem. Without map sensnor ecm uses tps for fuel corrections to run motor. Map sensor is right behind throttle body one bolt and one plug connection.
