I apologize for my complete ignorance, but...

If I were to pour TEC into the throttle body to clean the engine, should the car be idling or off? If it's all the same, should I run the engine to 2000rpm and follow all of the other procedures drawn out for the PCV method? Would it be more effective to spray TEC into the PCV or to pour it into the TB (or no different)?

Sorry to be a pest...
