The IC seals look good. Just had the intercooler off to change plugs/wires. Also checked when running with carb cleaner. Checked all the vacuum lines as well with carb cleaner. No change in engine speed/sound when sprayed. I'll check again.

Looks like I need to inspect the WUR.

One thing I don't understand with the WUR is how at cold temps with the fuel pressure lower the engine runs richer. I would think that higher pressure would mean more fuel.
