On my 04 mazda 3 5 door 2.3, with 72,000 miles i hear a ticking when driving just started a day ago. It only happens when i and just starting to push the gas. If i press it down the entire way no noise and if i let off no noise. only when i reach a speed and you keep you foot on the gas to maintain that speed. It sounds like ticking valves in the engine. it is coming from the passenger side. by the front wheel. It almost sound like a piece of cardboard is stuck in the spokes of a bike. HELP
