Hey guys i would love to have some help on figuring out what the issue is of why i keep getting the p0300 code. Iv changed the spark plugs, the coils have been checked that they are performing right. My horsepower and torque is alot less since iv been having this issue, and sometimes when gun it, it acts like its about to stall and then it picks up?? Any advice is appreciated... i had some ppl say it could be a sensor. Maybe O2 sensor. Thoughts?...
