    Yes, fuel pressure fluctuations can cause a random misfire. I bought a fuel line adapter off e-bay (UPR fuel line adapter) and a fuel pressure gauge (0 - 100Lbs oil filled) and mounted it to the fuel line and did a fuel rail pressure test and that will tell you if your pump is functioning...

  3. Ben Calimer Stage 4 MT-82

    I would put money on them sending you the correct transmission. I don't think Calimer is a shady outfit. When I had questions about mine, they got right back to me and reassured me that I had just what I ordered and let me know that if I needed anything different, they would send it right out to...

    Off and on rain all day so I didn't do anything with it, I was going to do another data log and send it off to the tuner. Sunday should be a better day for that.

  5. The Mustang chronicles continue

    When I had my tire shop a customer came in for new tires and one of the old tires had two plugs in the same hole and in the side wall. He bought the tires and two days later he ran over a piece of steel that went into the side wall, and the first plug didn't do the job, so he put in a second...

    I will never know what I was brought home from the hospital in. Both my folks have passed; Mom was 97 and Pop was 93 and I just lost my oldest brother by 7 years at the age of 81.

  10. What did you do to your S550 Mustang today?!

    I bought a UPR fuel line adapter and a pressure gauge so I can check my fuel rail pressure and see if the fuel pump, injectors, and fuel delivery module are all working properly. The parts came today, tonight I will start testing. I am still chasing misfire issues. I don't have any misfires, but...

    pull your intake tube and look at the throttle body for carbon and work the plate by hand and see if it snaps back after it is opened fully and released. It could just need to be cleaned if you have never cleaned it.
