I've neem getting a p0300 code for a week now. I'm going to change my plugs out tommorrow and see if it fixes the problem. Unsually though my stock injectors are clicking a little louder than normal. Hopefully it's just the plugs.

 

What injectors do you have stock?

Check the compression on the motor.

Fouled plugs might be the issue...

 

get it looked at bc i had the same code an not my motor is blown=(

 

What happened???

 

Just the stock injectors but i'm getting a clicking sound. I'm not sure if it's my injectors but it sounds like it. I'm going to get the Denso Irridiums and not the stock NGK ones. Anyone tried these yet?

 

What happened? Did the dealer warranty your motor?

 

it was brisk silver plugs for me maybe the same but diffrent plugs

 

How did you end up solving the problem?? mines started doing the same thing.P0300 code and even when i erase it with the cobb. it still have a rough idle and misfire on mid range and when letting go of the gas through the 5k to 3k rpm range. Im on stock cams. so im guessing its the plugs. what plugs did you end up buying to solve the problem.

 

Just wondering if anyone has found a solution that works for them? I have never had it until I got the car tuned two weeks ago, changed spark plugs to same ones ngk, upper and lower intercooler pipes, cold air intake, turbo back exhaust basic setup. got tuned and threw the code before I got home.

 

Fouled upper 02 sensor still random misses but lighter and not as often, ive changed spark plugs twice and bought a new coil pack to swap around. Had a boost leak test,(good) compression test(good).
