Manifold intake valve

http://repairpal.com/lincoln-repair-in-atlanta-georgia That is a link to some local shops for you to try. Sounds like you need a qualified technician to help you diagnosie your Town Car. A "sensor" is pretty vague, and the manifold intake valve (??? Idle air control valve?) is not going to cause a check engine light typically. As far as brakes - again, check the directory link I posted here and find a local shop that you can entrust with your business.
