Engine Cut

Question for Fix My Hog I would like to thank you for your website, you have a lot of great information. I have an engine miss at a constant load between 2100-2300 rpm, whether I am holding the throttle or using cruise control. I am planning on taking it to the HD dealer, but your website is so useful I wanted to check with you! My other question is, Is there a sensor that cuts a cylinder out at idle if the engine starts getting too hot?

Fix My Hog Answers Need to consider what you have for an air cleaner assembly and weather or not you are using a tuner. If you are using a Power Commander, Vance & Hines FuelPak, or Cobra FI2000, we would suggest looking into making an adjustment. Also, consider checking for trouble codes.

    Also replaced throttle position sensor. I have a 2006 Road King and chased a nasty engine miss at various rpms and loads. Idle perfect. I’m running a Power Commander V and have tried different maps to optimize my air/fuel. Replaced injectors as I had the 3-hole versions. Replaced fuel pump/reg, replaced plugs and wires, replaced intake seals, and cleaned air cleaner (big sucker, s&s 2-1, 508 cams, 88cu in.). Checked/ cleaned lo-voltage coil connector. Missing seems to be throttle position/ vibration sensitive. Possible have a cracked coil? I noticed that the high voltage nipped me when I got close to the plug wires when running. Cracked plug insulator? I’m running out of parts to change…any ideas? Things improved after changing the injectors, but problem has returned. Plug color seems about right, but I’m running a map that appears to have richen the mixture (intentional) for what appeared to be a lean miss?

      Thank you for contacting us.

      You might have a weak or partially broken connection around the induction module.
      Check for possible stored diagnostic trouble codes.
      If, by chance, you have a tachometer; disconnect and see if anything changes.
      Make sure battery cables are clean and secure.
      What you describe definitely sounds electrical.
