So as most of you may already know I have been getting my Integra back in stock shape so I can pass this damn BAR State Smog test. Anyways, I got home and parked it and I heard this intermittent (like every 4 seconds) snap sound coming from under the car. Like what you would hear as it cools down, that crackling. Only it is like evry four seconds. It goes tink 1234 tink 1234 tink, not a crackling, an individual tink ya know what I mean? Anyone know what this is. Just when I think I've done everything...
