I took the car in to the dealer yesterday for a check engine light.Turns out the car is running lean;which I've suspected for quite some time.I told them this 2+ years ago,they couldn't find anything then.Took it in a few months ago,they replaced the cat,still couldn't find any other problems.Now they're replacing my engine because of this problem.I'm thinking that I've been right all along,but hey it's under warranty.
