Pre-Cats? And Their Importance? Relation To Air Pump?
Well, might as well start asking questions!
I was looking around a thread about air pump removal said that it was for keeping the pre-cats clean or something of that sorts... Are the pre-cats THAT important? They sound like a another problem to me.
And do you need to do anything special tuning wise to remove them?
