I just checked my MPS because my car is running rich, burns a lot of fuel, and idles very poorly especially when warm. The CHT was bad and I replaced that. IT improved the stalling I had before replacing it, but the car is still rich and idles very unpredictably. I put 15mm Hg on the MPS and it lost about 1/2 mm in the first minute and 4-5mm within 5 minutes. Would that be considered a bad MPS. If so does anyone have experinece with rebuilt units from AA or Preformance Products. AA is about $40 cheaper. Thanks for any input.
