I am rebuilding my motor 76 2.0 and checked the MPS today. It sucked on it and it does not hold a vacuum, from what I have read it should hold a vacuum. My engine was running before the rebuild and I don't see how it could of got damaged when I removed it.
Do I need to replace it? |

If you follow the included directions to replace the diaphragm and seals included in the kit - the MPS will operate as it did before the diaphragm failed.
 If you replace the stock stop screw with the one included in my tuning kit, and you install a wideband air/fuel meter in your car, its fairly easy to improve the overall tuning of your engine.  |

Chris and everyone Wouldn't a wide band air/fuel meter be overkill for my stock engine (what do they cost, I am a poor European with an expensive hobby). Could someone PM me Tangerines diaphragm installation instructions? I have read the strip down and tuning instruction for the MPS on Rennlist it seems pretty straightforward. However some equipment is required a vacuum pump an LCR meter,. The LCR meter recommended on Rennlist costs about $350the the cost of these products plus the diaphragm kit make it cheaper to buy a reconditioned unit From AutoAtlanta, although this would be not as much fun as repairing the unit myself. Question: If I replace the diaphragm do I need to calibrate using a LCR meter or is there a workaround? Thanks |
