My 02 Lincold Towncar won’t hold an idle. The car will start, but if you’re not holding down the gas pedle, it dies. The engine Lite is NOT on. Any idea what it is? Thanks, Keri

It is almost certainly the Idle Air Bypass Valve (also known as the IAC). Fortunately, they are both cheap (< $80) and easy to replace (two bolts, one connector, and one hose) on the 4.6L engines. The newer ones are throttle by wire and don’t have an IAC to fail.

You were right. I purchased the part you suggested and installed it. The car started and is running like a top. This was fantastic and I want to thank you so very much for being here. Keri
