I have an '03 TL Sport model. I love my car and take excellent care of it. Recently I've noticed a ticking noise coming from the engine. Sometimes it's louder than others. The Acura Service Center tells me it is the Purge Valve and there isn't anything I can do about it. I've made several complaints. They even tell me that it's on a lot of the newer cars as well, but how could they sell them that way? To me, my car now sounds like a bucket of loose nuts & bolts. Are they telling me the truth?
