I have 71,000 miles on my Ridgeline and I have a engine knock or ping I think. Happens when I accelerate, around 2800-3000 RPM.. I can feather the pedal keep noise going, if I accelerate hard no noise. Tried no ethanol gas and 93 octane. Neither helped.. I'll check exhaust shields this weekend..but think it's not.. Anyone have this issue or ideas ? Thanks..
