It says it covers certain 2003 3.9L V8 LS models and covers the COPs and valve cover gaskets for 10 yrs/100K miles. All the dealer has to do is run an OASIS report and it will say whether it's covered or not.

I purchased the 03 model 3.9 V8. private party. The beast ran a little rough, so .... Diagnostic says .. cylinder 8 miss fire. I know the car is 7 years old so maintenance is a given. I was going to take it up to Akins Ford that week to have plugs changed coils etc.... Boom! 2 days prior to my appointment, I am at a store and went inside for 5 minutes. Turn the key. Zip Nothing Ziltch. All the lights.. radio full power. Tow Truck action.(Insurance covered) Battery? Ground wire in trunk that someone in here mentioned? DDCV? Well...They said "A" Battery cell was dead.. I live in Athens GA and the Company "akin Ford" on ATL Hwy covered ALL the parts/labor for the plugs coils and gaskets. So FYI....Ford will cover it. It must be a reoccurring problem. Jaguar situation. I am very impressed with the service with Akin Ford. I'm one hell of a cynic.
 
Wow! What a difference. No hesitation what so ever. This baby rides smooth for the LS. A great mechanic can tweek it. Now I need to be careful because if I touch the gas peddle .....Vroooom. Now that's what I'm talking about!

Yeah I've been there playa. I replaced all valve cover gaskets, all ignition coils, all spark plugs and problem was solved. My pockets felt the pinch though. The key is the valve cover gaskets. They are the culprit.

I have replaced both valve cover gaskets ($600), but the miss fires are still happening. Dealer said they cleaned the oil from plugs and wires. Seems misfires happen at low speeds, accelerating and hills. I didn't replace the plugs during the gasket change. Sure would be nice if I could find out if there was/is some kind of
recall or (free) dealership fix for this problem. 2001 LS 88K

There is no recall or extended warranty on a 2001. You need to replace all of the COPs (coil on plug). They were damaged by the oil or they just wore out on their own - either way you need new ones. Best to just replace them all and get it over with.

Not sure exactly - never had to replace mine. I know you don't want the really cheap ones on ebay. I'm thinking they're in the $40-$60 range.
