Having problems with your 2001 Mercury Villager ?
Checked at autozone when service engine soon light came on code for knock sensor and fuel running rich came up...are these expensive to repair?
The knock sensor is located under the intake manifold and will be expensive to fix at 5-6 hours labor. The rich code could be a bunch of different things and will need to be hooked up to an actual computer to see what is out of spec.
