Hi All,
My Mazda Protege5 is my commuter car, and is a stock, high-mileaged and well serviced car. It's got 148,000 miles on it, has seen regular oil changes at 3000 miles and plugs at every 30k.
I've noticed intermittent pinging at low RPMs, especially at the 1-2 shift around 20 mph. I'm using 87 octane gas from shell/chevron, and the pinging isn't quite as bad with 89 or 92, but I can't help but think that something needs to be checked here.
Anyone on the board have low-rpm pinging in their p5? Power seems adequate given the lackluster base output of the car, but perhaps I'm gradually losing a bit due to a cat or other?
Thanks in advance!
