Hey all. If you recall, I was having rubbing issues with my driver side tire. Well, I put a 2" front leveling kit in and it fixed the problem. When I was in the engine compartment there was this coffee can looking thing on the passenger side on the wheel well. That got touched a little while putting the leveling kit in. After we were done installing the Bronco would dog big time when I stepped on the gas. I popped the hood and was looking to see what was wrong. I pushed on the wires to the coffee can looking thing and then the Bronco ran fine. Does anyone know what that thing is? I do not have a owners manual so I have no clue!
Thanks in advance
