Truck Pinging?!?!

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.
