Yet one last timing question. So I did a bunch of work and you can go back to a previous post that I have. Long story short I went ahead and returned it and I end up being just a tooth behind my timing mark on my chain so I am assuming it needs to be timed one tooth ahead to advance it still. How do I know that is I laid my chain out me to links on the end painted one link on the far end on both sides and that gave me my even number for my timing marks to then line up on my cam gear tooth is one tooth click behind mower one painted mark.

My question is this is one tooth back still enough to cause a P0 0 12 code? My next question is after I drive the car and the car gets warmed up it runs and idles fine little bit of hesitation on 3000 3500 RPM but that is to be no with the tooth behind in timing now after the vehicle warms up it starts to hesitate and start knocking. What I noticed is it will get a low-key Idol but once I read it once or twice it won't idle smooth again and it will be that way until you drive it for a while and then it will start acting up again it never will shut off and it runs fine. Any help will be highly appreciated thank you.

05+ mustang use cam phasers to adjust cam timing on the fly. This adjustment uses a fixed crank timing signal to ensure optimal cam timing at all RPM's.

Yes, being a tooth off could affect the cam phasers ability to compensate appropriately. They have a very wide range (+/-60 degrees) but with one tooth being off you could be exceeding the cam phasers adjustment capabilities to compensate, the the hesitation.

Well I will be fixing my one tooth issue this week. I decided to leave the car alone and do another project so I would get frustrated with the car.
