:pat: Well,I was spraying my throttle body and intake with cleaner.Of course both hands were busy,one holding the can,the other holding the throttle open.The little red tube shot staight to the back of the plenum.I figure I'll give it a good cleaning while it's off.So,what's the best way to clean it?Can you guys give me some hints.The spray only does so much.Thanks,Doug

 

Have it hot tanked, local shop should know where to get this done. Should be cheap and save lots of scrubbing.

 

Oven cleaner works great, just don't let it soak for too long. Doing so will discolor and actually eat the metal.
