I got the Rodeo back.

- They pulled the intake, looking for carbon.
- The pull the plugs, looking for carbon.
- They checked for loose bolts on the cam gear. Thought that was odd, given the known cam issue. Though, they didn't mention that a few have snapped.
- They recommend haveing it decarbonized regularly, and using an injector cleaner. When I told them I did it myself, last month, and spent $40 on fuel aditives, they didn't respond.

Next, I call Isuzu, again. I will not chip away carbon at EVERY oil change. I'm told no one else does... Why should I??
