Hello, I have the same case with my sonic 1.8. Random misfires without codes. My spark plugs were original AC Delco installed in November 2023 and I replaced the coil pack a year or so ago by the same ENA. I made a mistake when I installed it since I did not use the dielectric grease and when I removed them I noticed that the inner plastic part was affected. However, according to what I have investigated in many forums and videos, the sonic is very sensitive with parts that are not original, the original coil has to be the DELPHI or acdelco brand, both available on Amazon. I'm going to order the Delphi coil to see if it solves my problem.
@@sideyardmechanic I'm really a bit desperate, those push-pulls feel very bad and even more so that in my country there is more traffic than free passage. I even went to a place to have the catalytic converter checked, they put a camera in it and it looks partially clogged but very little. I even thought it could be the cause. what do you think?
I would also check fuel pressure, inspect and clean the throttle body and Mass air flow sensor. Those have caused me problems in the past on other cars.
How do you know it is not one of the injectors? My car is doing the same you just mention, jerking while idle (at a stop). The spark plugs are supposed to be new, not sure about the other part. It is a Chevy Sonic 2016. Appreciate the help, thanks! Nice video btw
Thanks for the question. Spark plugs are easy to change and are a serviceable/ wear item. They only last so long. The same goes with the coil pack. On older cars you would change plugs, wires, and distributor cap during a tune up. It's not to say that you can have a faulty injector, but I would think it would give you a rich or lean code. Good luck
Thank you so much for taking the time to reply back to me. Unfortunately the Mechanic guy does not check anything unless there is an error code. And I am also not getting a rich/lean error code. I'll keep you posted. :)
👍exact problem with my sonic, i dont beleive my mechanic said,well there's no code so i dont know
Hope you were able to get it fixed. Yep some issues won't trip the CEL. Good luck 👍

@@sideyardmechanic How many PSI should the fuel pressure be?
@@enmanuelabreu3368 should be around 60psi +-10psi
Nicely done
Thanks for the view and the comment
