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,
Vacuum gauge to port on TBI or intake.

I will get one tomorrow and check. I'll update as soon as I'm done.
O.k. got a gauge at lunch and checked. It's showing 17 and slips to 16 when stumbling at idle in Park.
