    Not you, Rally! We need to know a vacuum or MAP reading. From what you said your MAP sensor sees a low vaccum reading.

    Other than checking MAP with my laptop is there another way? Also how do I check the vacuum? Sorry, ignorant on this.

    Thanks,

    O.k. got a gauge at lunch and checked. It's showing 17 and slips to 16 when stumbling at idle in Park.
