Hey guys! I have a 2003 TL Type-S with 80k miles on it and have just recently developed a small problem with it. I changed the sparkplugs today (NGK Iridiums) and when I fired up my engine and took it for a spin, I noticed a faint ticking sound when accelerating. It's pretty annoying to constantly hear whenever I accelerate, and it's loud enough to be heard while driving the car. Even if I tap lightly on the gas pedal in park it still makes that sound. Is it possible it's somehow related to the sparkplugs? I think it would be too a big a coincidence otherwise as it only appeared directly after changing them. My dad knows about cars and he thinks it might be related to the fuel injector, but I want to know what you guys think.
Thank you!
Thank you!
