I was able to get the fuel rail freed up enough to pull the #8 and #9 injectors. I ran them both through an ultrasonic cleaner for about 20 minutes and swapped them, so what was the #9 injector is now in the #8 cylinder and vice versa. So one of three things will happen…
- The problem is gone, meaning the ultrasonic cleaner fixed the problem.
- The problem moves to cylinder #8, meaning I need to replace an injector.
- The problem stays with cylinder #9, meaning I probably have a bad coil pack (which is still under warranty). There is a very remote chance of a bad plug on #9.
To avoid uncertainty, I am considering swapping the plugs between cylinder #9 and #10. I am however NOT a fan of pulling the coil pack again… if everything else goes well this afternoon and I have time to do it, I’ll do that
