I have a 2.2S and from time to time there is a tick noise that is apparent when coming to a idle rpm. It is random and seems to be getting louder. The engine has about 110,000 miles and has never been rebuilt. Does anybody ever have this type of noise from their engine? I wonder if it is the quality of the Gas we are using in California or is it a timing issue? Regards Chris Early S Reg.#205
