this is the same problem i have lol brand new ngks only i used g-powers, i would give advice on how i fixed mine only im not 100% sure i fixed it at all, just seemed good for the short test drive i did, i just reinstalled all the plugs, checked all the gaps, cleaned the coils, and made sure everything was tight, good luck

you can see if its throwing codes yourself. turn the car to the on position then hold down the trip button and start it and keep holding it down till it says test. after that you can hit the trip button to find what codes are being thrown

are you kidding me! lol that would of saved me half a tank of gas if i knew that sooner
