On my 74 2.0L, I have MPS (Part#: 280 100 043). I am not having an existing problem with my MPS, but with today's gasoline (ethanol blends, etc..) should an MPS be recalibrated for optimum operation? I typically fill up with Chevron 91 premium.
Of course, if it's not broke then don't fix it... |

I use 87 octane as that is what the car was designed to run on. Save the money and add a wideband A/F mixture gage. You will then know if you need to adjust your MPS. I have a 76 with a calibrated MPS but was still running lean until I made the adjustments to richen it up.
Just my $.02 |

Just my $.02 Hi - I'm glad this issue has come-up because I just bought a '76 2.0 with injection and pollution controls intact - found on 914world! I wasn't sure what to run and the previous owner had said 89 at most. I had assumed I should run higher and the little sticker in front says 91 but the octane rating were different then? Thanks. |
