Hi everyone, I get in trouble with one of my motors few weeks after ago. It lost a power, still running, but shakes and get more as 28k rpm on full engage. I replaced an injectors and spark plugs just to be sure they a ok. Still same. So when disconnecting plugs on injectors, I figured out so bottom one , witch is #4 cylinder, not makes and differences. So that’s mines it’s misfiring. Anyone had some similar experience?

Well you got it down to the cylinder, so either no spark there or no fuel. Good luck, but aside from replacing parts you are probably 90% there.

Oh, and I assume your 28k rpm is a typo! That would be really racing 5x faster than it should go!

Thanks everybody for responding. Will check few more things and let you know. My next step will be electrical check up. There is any simple way to check ignition coil without having remove it?

Hi everyone, So a check a signal in each injector and spark plug, all good. Check a fuel pressure, looks good. ☹️ Then I asked mechanics to come over and do things, what they can do with computer software. His checked again all stuff, also intake calibration , sensors, timing… nothing. I’m lost as is now. Order another service. They said - injectors. Took them out and will clean. I not very believe in this but hope for miracle 😎 Thanks

Sorry this one has been such a challenge. Once you get it figured out, having it working will be that much sweeter! Please keep the updates coming so we all hear the final end of the story!

Just swap the injector with another cylinder. If problem follows your injector, you have your answer. If you have twins I’d swap with one from the other motor and see if it runs correctly instead of putting a problem in another spot, but both techniques should work.

Hi, After some time I’m giving tip, what work for me. DO NOT believe, so new injectors is good. Mechanic took all injectors and sent them to clean and test. And two was completely defective. So I spent little bit time to switch them with other also new and engine just run as should. Kind a sad story, but I definitely learned from it.
