Hi, Against my better judgment, I had the timing belt/water pump replaced by a 'friend of a friend'. Now, the engine seems to be a bit down on power and it's got a pretty noticeable vibration at speed. I know...I already feel stupid... :) I took it back to the 'friend of a friend' and he rechecked to see if everything was lined up. And..lo and behold...he says all is normal. UGH! While I'd like to administer a baseball bat to his cranium, I know that it's ultimately not worth it. So.... Any tips for a fellow Honda man?
