I've noticed in the last few months that the 2nd cam doesn't have the "kick" that it had a year ago. My Elise ('05) seems to be as fast, the engine runs fine, I replaced the air filter recently, but the 2nd cam doesn't have a big difference as before. I can feel the second cam at about 6.8K, but it it doesn't "kick" much. Is it wear (The Elise has 32,000 miles)? Does anyone notice this in your Elise?
