  1. Light Hickup / Stumble with onset of light throttle

    Does your tach jump a couple hundred rpms? Kind of twitching?
  2. Shudder / Shaking Misfire Under Load - not spark plugs

    I'm not sure, but when I looked up replacements on the Internet, none of the images looked like mine. Maybe there is an improved design. My engine was built in January 2014. I think I will stop at the Ford dealership and see if there is a difference. Mine had a carbon like buildup on it as well...
  3. Shudder / Shaking Misfire Under Load - not spark plugs

    Ran pretty good to NC. Not perfect but 80%. I think I will buy a new T-MAP sensor when I get home. It wasn't annoying like before, just felt it every now and then. Even then it was less noticable. Jerry
  4. Shudder / Shaking Misfire Under Load - not spark plugs

    I'll know pretty quickly once I get in the mountains. I put about 100 miles on her today without a hint of the shudder/mis I was getting before.
  5. Shudder / Shaking Misfire Under Load - not spark plugs

    Can't wait to hear what they find. I replaced coils on mine just so I can say it's not them. After reading some of the F150 & SHO forums last night regarding similar symptoms, I pulled my cold side hose and checked for moisture or oily residue. Found nothing. However, I did find that the...
  6. Shudder / Shaking Misfire Under Load - not spark plugs

    89 no solution Well after a 4 and a half hour trip each way to/from Chicago using 89 fuel, I can say it's just as noticeable as with 93. Jerry
  7. 50th Package Wheels

    I did the same I did the same thing. The 255 40 19 is more in general than the 235 19. There is a pretty good used market too, if you look around. Take offs are not too hard to find, but kind of a pain getting them to the tire shop. But, I like this style of wheel and I can still use an all...
  8. 50th Package Wheels

    I put some 50th package wheels on my pony. I really like how a bright wheel makes red pop. The wheel & tire combo is 4lb heavier per wheel than the stock 18". Jerry
  9. RACE RED S550 MUSTANG Thread

    50th Package Wheels I put some 50th package wheels on my pony. I really like the way bright wheels make red pop. Jerry
  10. Shudder / Shaking Misfire Under Load - not spark plugs

    89 better I'm on day three of using 89 instead of 93. Been through a tankful and just filled up again last night. The mis-fire feeling is still there, but if I wasn't already sensitized I don't think I would notice it. When going up a hill at a steady speed, I now get more of a typical loaded...
  11. Shudder / Shaking Misfire Under Load - not spark plugs

    I do think mine is better when cold. Or before it's warmed up. I've always used 93 but I'm going to try 89 for a few weeks and see if there is any difference. The misfire seems like it has too much spark advance. Then drops back when giving it more pedal.
  12. Shudder / Shaking Misfire Under Load - not spark plugs

    My 2015 automatic has this same stumble/misfire like problem. I feel it when I go up overpasses or slight rises on the road. Only seems to do it upon a slight load. Very annoying. I had the Brisk plugs one heat range cooler for about 15K miles when this started. I replaced them thinking it was...
  13. Catch Can question

    Mishimoto plugged up I've had my Mishimoto cc for about 65k. This past week I had two codes show up for pcv. Drained my cc. Normal amount of water and oil came out. Took the cc off and apart. Approximately a 1/4 of muck in the bottom. Found the bronze filter element was almost completely...
  14. Brakemotive rotors

    Nice rotors I just replaced my fronts with the Brake Motive drilled and slotted rotors with ceramic pads. Really great brake feel and good looking too. Price was great. Jerry
  15. Blow off sound by disconnecting recirculation tube

    What I did I added a short red silicone hose and a modified Edelbrock breather to my BOV/DV. It looked unfinished without. Jerry
  16. 2.3 Mustang Ecoboost Lightweight Billet Water Pump Pulley from MMR

    Got 40,000 plus miles on my MMR pulley. Still looks nice, even after last winter. Jerry
  17. What did you do to your S550 Mustang today?!

    MMD Winglets I added some MMD winglets to the front today. The box was on my porch when I got home. Jerry
  18. MMD Splitter Winglets

    I had to try some of these. Here's a couple pictures. Jerry
  19. AM fog light splitters by MMD

    Better angle Here's a better angle. Jerry
  20. AM fog light splitters by MMD

    Made some I made some from 1/4" think dark tinted plexi. They screw to the bottom of the turn signal. I made one just to see if I liked the look or not. It turned out great, so I made two. Softened up the edges with the sander and polished. Jerry
