    SO for some strange reason my truck has spark knock aka pinging. I discovered it the other day when I have my foot fully on the brake at a stop and I keep pressing the gas pedal like pulsating it, I hear spark knock! It has new plugs just put in 60miles ago gaped right as well. Could it be bad gas? Help me :(

    Oh ps no CEL

    Could it be fuel injectors? I hope not because they are expensive! I also read about dual tip spark plugs are better? I dont know why cause the stock ones are singles. I put in the denso titanium tips after reading great reviews. It did make my mpg go up.

    Also is it normal to get 250miles on a tank driving mostly city in a 2rz?

    What kind of plugs did you put in? I had problems just like you are having but then I replaced them with nkg and denso plugs and it runs perfect.

    iirc, the OEM spec plugs are dual ground plugs, not the single. I have heard from taco owners that single ground plugs can cause problems...although I have single ground plugs in my taco and causing no problems. But when it comes time I will probably get the dual ground plugs just for peace of mind.

    What Octane fuel do you run?
    First start with putting a bottle of SeaFoam in the tank.
    Carbon buildup can create hotspots that can cause pinging.
    If you are running Reg, try Plus. If you are running Plus, try Super for a while.
