Yes do keep us posted.
Hope things turn out well for you.

Got the report back from the shop today. Looks like everything looks good from a mechanical perspective on the timing. Unfortunately, that means there’s some sort of deeper issue and the mechanic thinks it has to be the timing chain actuator/tensioner. This part alone is over $1200 and it’s about 10 hours of labor to put it in. Bill just over $3k ....

I’m going to go ahead with it because his analysis makes sense from what I’m feeling with the car. It starts and drives just fine so I don’t think I’m getting a consistent misfire. It seems like it occurs in specific gears/rev ranges and just feels like the car is very low on power. My assumption is this is occurring due to one cylinder bank advancing/retarding valve timing and the other not acting similarly. He’s going to work through getting to the cams and will report if there’s something simpler going on (ex: the plastic guides on the tensioner failed instead of the whole part).

Hopefully this is it and I can get out on the Blue Ridge Parkway in the next couple weeks. Wish me luck.
