C7XR7

I've noticed that in our 2010 Limited AWD but only when driving with the OD off.

Mercury summer cruiser.

The twenty elevens look like they are going to have some nice technology updates as well as interior upgrading. Dealing for a 2010 should be pretty good with the 2011's coming out very soon. We did the numbers and using the 0% interest rate was the ticket for us as well as having some good down money to apply. I don't usually like to buy the first year of the new technology but I think the 2011 will be okay in that regard. If you can afford to wait and you want that "new stuff" then go for it. I am looking forward to big mileage improvements over the next 5 years. EcoBoost is nice.

If I had sticking lifters after only putting on 4100 miles I would be livid. I think something else is a problem here and if it needed injector cleaner why didn't the dealer provide it under warranty? I would lean toward an electronics problem and I wouldn't stop until the dealer repairs it or refunded my purchase price.
