    Great video! Really like the trouble shooting and explanation of the job! I had to put tape over my aftermarket stereo alarm it was to loud also. That record button plays hide and seek with me too 😂 Happy Easter 🐣

      Oh yes definitely cheaper than a new truck. I’ll keep this one going as long as I can..

    I had a misfiring '98 dodge ram, if you watched the engine running at night in the dark i could see arcing out of the spark plug wires where they were close to the block, got some good aftermarket wires and cured the problem. But 13yr old plugs i wouldn't trust.

      Was definitely time to change the plugs. They’re said to last 100k but honestly I should have changed them sooner. I noticed a rough idle starting last year.

    I have the same code on my 2010 Nissan versa. I also have a hole in my exhaust near the upstream(air/fuel ratio) 02 sensor and have been getting a code for the o2 sensor as well. Could the O2 sensor issue be causing the misfire?

    • @DIYWilly
      @DIYWilly  Před 26 dny +1

      No wouldn’t think so. You should get the hole in the exhaust plug welded. That may correct the O2 sensor code. Try the simple troubleshooting for the misfire. Move the plug and coil to different cylinders and watch the code. My guess is you have a tired coil. Thanks for watching!!

    Good one! This reminded me it's time for some fresh plugs in mine too. If the coil isn't too pricey, I'd replace it. I'm planning on replacing the coils on mine when I do the tune up, but it's only a 5 cyl GM and the coils are cheap for those. Your engine sounds good to me. I didn't hear any misfires at all?

      Yes the engine is definitely running smoother since replacing the plugs. I moved the coil but the misfire stayed with #4 so not sure what that means. I believe the coil is fine.

      @@DIYWilly I wonder if it may have a little carbon build up on the valves or seats in that cylinder? A good dose of Sea Foam is never a bad idea regardless IMO.

      I would much rather there be carbon buildup than a damaged lifter in the AFM system.

    was it a fuel injector

      Hello Vic, No it was the spark plugs. I’ve already changed the fuel injectors when I had the 219A code. Thanks for watching!!

      This is where it can get scary. We all know about the AFM/DOD problems with these engines. I hope this is not the problem you’re having. Thanks for watching!!

    Hello, Are you interested in testing our products? We would like to invite you to test the Air Vent Windshield for your Polaris RZR XP 900

      Hello, Normally I would say that I’m interested in testing your products. However my Polaris RZR project is a body swap and will no longer use many RZR type products. Thanks for watching!!
