I bent my rad support into the front valve cover and it caught 3 valves.
The timing marks were definitely aligned when I put the cam in 3 years ago.

What about other things like small vacuum leak or PCV issue? I have a hard time believing a stretched timing chain would only manifest itself in no-load conditions. Not saying you're wrong... just thinking out loud.
I have checked the PCV valve and theres no way any of the ports are clogged.
My vacuum is the same as before too.
Not trying to shoot down ideas either, keep chucking them at me.
Also, what about leaky injectors?
