What is the best thing to use when doing these 2 areas seeing as they are plastic?

Woould BG406 be too harsh ???

 

sea foam seems to be the trusted cleaning chem. if your brave enough remove the intake manifold and get in there with a pick, best way to do it with out a walnut shell blaster.

 

Use Purple Power or Simple Green in the intake manifold and throttle body. It's just oil that's built up here. It'll clean that oily residue off amazingly well. Use a spray bottle with water to rinse it out. Be careful not to get the throttle actuator wet. Dry it out with some compressed air.

I used Seafoam and some other carb cleaner in the intake ports to attack the hard carbon buildup, but nothing works as good as some scrubbing with a metal brush. Someone else mentioned using cleaning parts from a gun cleaning kit which is actually a very good idea to get in those tight spaces around the valve.

That's the kit I am thinking of using.

 

If you take the intake manifold off could you try and shoot some
pictures for us not too mechanically inclined folks. I was thinking of
doing it but some pictures would proabably ease my fear a little.

Thanks
