My Lincoln navigator 01 has a check engine light, and it stall at times when accelerates. Gave a po 174 code. What needs repair and an estimate of cost please. Purchased new, it has 166,000 miles I've kept up maintenance best I knew Thanks

We will first need to do testing on the vehicle to determine what is the problem and then provide you with an estimate for whatever that repair needed. We would be happy to get you in as soon as your schedule permits. Atlanta Car Care 2816 Buford Highway NE., Brookhaven, GA 30329 404-325-0063

this is almost always caused by a severe vacuum leak. They usually happen at the rubber elbows and connectors that supply large vacuum pipes for things like the PCV and brake booster. Listen for the HISSING noise with the engine running and follow it to it's source. They are usually well hidden on the bottom side of manifolds and throttle bodies. engine has to be running because the vacuum sucks a hole right through the connector that closes up when the engine shuts off.look and listen,and you should find it.Vacuum hose is cheap!! you can do this!!
