KA24E ROUGH IDLE FIXED - 1990 Nissan 240sx

Just started my 240sx today and am starting to have a softer version of what you’re experiencing. I’ll troubleshoot it with this in mind! This means a lot, more than you can imagine, thanks friend :)

@@guitarforall well I started the car up yesterday morning and the vehicle was shaking harder than usual. I found a couple of issues. It seems I’m having a misfire on cylinder 4. I also have a leak on a vacuum tube after where the EGR used to be.

@@xXUnDe4dK1LL46674 good diagnostic. at least you know what your aiming for. i started working my way from the outside .. to inside. so i checked my MAF sensor, air filter , hose clamps , spark plugs, spark plugs firing order , then the injectors.

Awesome video! I am currently experiencing the exact same issue on my 1990 240sx s13. I am actually very surprised by how spot on your issue looks to mine. I changed fuel injectors and sure enough I was missing O rings. Unfortunately, it still has the same issue and I'm still trying to get my ka24e to idle. My s13 sat for 15 years in a backyard so I guess my next project is replacing all the old vacuum lines. 🙁

@@lylepeckler7163 thanks for watching! doing a smoke test definitely helped check for leaks as well. luckily i only had 2 leaks. make sure to clean out your sensors and maybe the air filter as well. there is a ECU in the passenger kickbox that blinks red and green , those signify check engine light codes. my code was 45 which meant ‘injector leak’
