Drove the wife's '02L last weekend. It was hot, humid, and sticky. I fear I heard detonation (several times) under mild acceleration from redlight with A/C on. Could not reproduce sound with A/C off, nor under hard acceleration with A/C on. Only from redlight to redlight. Sounded like valve clatter on an old Chevy I used to have when I burned regular gas instead of premium.
Is this something serious enough to warrant a visit to dealer? We have an appointment for tomorrow. I HATE to go to dealer. Service writer did not even know what SVT stood for. Had no clue about free loaner program. Said we would have to take that up with their rental department. I HATE to go to dealer, but don't wanna break a piston or something.
Truck is TOTALLY stock, down to stock air filter. Has 12,000 miles on clock.
