Rough when cold.

[Ryanlsc123]

To all the LVC gods.....

I have a 2003 ls, V8, 120,000mi. And I have a problem...

When my lincoln is cold (ie. sat longer than 4 hours since it has been run) I will start it up to go somewhere, and it has a hesitation at minimal throttle to the point it sounds like it will cut out.. If I give it more throttle it will smooth out and run fine.

It also has a bit of a lag when warm and you mash the gas away from a stop light. But if I drive normal it seems ok... Please help if you can....

Step 1: Replace all COPs (ignition coils) and spark plugs. *

This will resolve your symptoms most of the time. This is also a very common LS problem.


*: If your 2003 LS was first sold or placed into service later than February 2003 and you have less than 100K miles, a Ford/Lincoln dealer will stress test the coils and replace any that fail at no charge. If none fail (some will, count on it), then you will have to pay about $100/$200. Also since it is an 03, they will replace the valve cover gaskets if they find oil in the plug wells, if this has not already been done under warranty.
