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.

ok, did it run fine before?
Do the numbers for the ECU and MPS match? tell us in detail about your engine/FI with the numbers on the ECU, MPS, CHT etc. The vacuum numbers sound ok to me so I think your rich problem lies elsewhere.... Temp #1 sensor still plugged in? Fuel pressure ok and at 29-30lbs. Too high (50lbs+) means the return line are kinked give us more to work with here....can I buy a vowel??? |
