    I red on this forum that it was possible to clean inside the crank sensor (MAS)
    because it could cause ignitions troubles.I still have my cutting out cylinders problems so today I decide to remove the crank sensors to clean it.
    I dont understand how to clean the inside because it seam to be one part made, not possible to seperate any part of the sensor ??
    any explaination ?
    thanks
    nico

    Are you sure your talking about the crank sensor and not the Mass Air Flow Sensor (MAFS)???? The crank sensors are on the bottom front of the engine. The MAFS is located on the top of the engine just after the air boxes, or between them depending on the year of your 355. If it's the MAFS you are talking about you can use electrical contact cleaner. It usually comes in a spray can.

    The 'crank trigger sensors' are a magnetic type I believe, so dirt should not affect them..... :)

    Yes, you have two of them. Be sure to also clean the connectors for the MAFS.
