Engine Performance problem
2001 Cadillac DTS V8 Front Wheel Drive Automatic 141000 miles

My cars will not stay running without me pressing on the gas. When I stop giving it gas it cuts off. I have a full tank of gas and never had problems before.

Do you
have the same problem?

Could have a large vacuum leak, egr stuck open, or a leak after the mass airflow sensor. Try disconnecting the mass airflow sensor and see if it idles.

Look at your cars throttle position sensor and idle air control valve. These two will make the car hard to start or not start at all because it was located in the general area of the intake manifold right where the throttle cable connects. Hope it helps.
