The Leo Bug
Ok, so i recently got my timing belt/water pump replaced and they said that they had also fixed a vacuum seal or pump or whatever and I was wondering #1, what is this exactly and #2, does this have to do with the spark plugs and If they would have gotten changed out (and is there a way to tell?). Now my check engine light is on again and I got the code P2187 and all i could find out about it is it means System Too Lean at Idle Bank 1. What does this mean?? I'm trying to figure it out on my own so i don't have to go back to the shop and spend money on something if its an easy fix.
