Asked by Mar 08, 2014 at 10:33 AM about the 2003 Cadillac DeVille Base

Question type: Maintenance & Repair

I have a 2003 Deville and was warming it up 15-20 mins before driving during these winter days. Now it appears (maybe a coincidence) that I ahve a fuel line problem. IT cranks up with no problem electrically but "putters" out once I stop accelerating such as at a stop light. Any advice would help and thanks.

Does it start right back up? Will it stay running if you give it a little gas? If so possibly idle air control valve dirty/faulty or dirty throttle plate. If no possibly pcv valve or egr valve sticking open.

Yes, it will start back up and stay running as long as I push the pedal, once I release it putters out ...thanks for the quick response .

I would look into cleaning the idle air control valve and the throttle plate.

No it's something you can do with just regular tools. Most idle air control valves are held in place by two Philips head screws. As far as the throttle plate goes when you remove all the plastic duct work from your air filter to intake the throttle plate will be right in the front edge of the throttle body.

After looking at a picture of your IACV it should be the same with two small screws holding it in.
