Thanks for the replies! So if not turning two full revolutions caused a slip, how do you suggest bringing it back to the correct timing?

One thing- while trying to line up the marks on the camshafts we bypass them on first turn turning clockwise, interested of making a full turn we went counter clockwise to align.

Dual overhead cams The lines on the cam sprockets were aligned, sprockets locked with the tool kit. Chain wasn't removed from the sprockets. Evething was marked, sprocket, chain the only part remove was the cam shafts. Intake removed first, replaced rockers and put back in, remove exhaust cam, replace rockers. Two factory dots on the sprocket and the cam so we put everything back to our marks and also was super to line with the factory dots. Once we started up again the engine was shaking and sputtering and the exhaust smelled almost like sulfur. After that we changed out the sparkplugs and coils and it felt a little better but is still misfiring.

Thanks for the reply! We did purchase the tool kit with the plastic shims to use when changing out the rocker arms. Seems like we will have to pull it apart again and start over.

Everything was marked before being removed and put back in place. The marks were done with a paint marker so a thicker line leaving room for error. Is there a way to test that the timing is correct?

2014 3.6 93,000 km Was running fine until the rocker arms started ticking. Changed out the rocker arms and once it was back together it was misfiring and shaking code was P0300 Changed out the sparkplugs and Ignition coils, now it will idle normal for about 20 seconds then it starts misfiring and shaking. Check engine light goes from solid to blinking to solid.

Replaced cam shaft rocker arms, once everything was put back together engine started shaking and misfiring. Code P0300 Replaced sparkplugs and ignition coils. Upon initial start sounds ok for the first 20 second then starts misfiring and shaking. Code still reading P0300 Check engine light is going back and forth between flashing and steady. Not sure where to go next with this, help is much appreciated.
