Ticking Sound Only When Accelerating

[Caddyman]

It does sound like spark knock…It could be a faulty detonation sensor or there is carbon buildup in the combustion chambers. Let the tank get down to 1/8, add a bottle of Techron and take it out and do several full-throttle accelerations up to as high a speed as you can manage. This should “decarbonize” the engine and eliminate the detonation…
