New post yet related to my earlier posts on weird compression readings. Thanks all who posted to that thread. It turns out I had mid-timed the cam by nearly 20 degrees. Weird as this isn't my first rebuild. At any rate I carefully set the cam timing with #1 cylinder on TDC, the cam gear arrow pointing down and the blue links on their respective teeth. Everything lined up as one would expect on a new chain and gears. The engine starts hard and misfires back through the airbox. It is as if my sparkplug wires are wrong yet they are correct. Plugs are new. Once running the RPM will rev, yet very sluggish. Once the RPM drops below 2000, the misfires kill the engine. Their were two codes. Airbox inlet temperature too high and Mutiple Cylinder Misfires. The Airbox temp code repeated after code erasure. I even checked the visual timing on the cam by pulling the #1 spark plug and the right tappet cover. The sequencing on the valves looked appropriate. I'm stumped.
