any buddy familiar with these codes 300,301,302,303
 

My mechanic says my car is throwing these codes 300,301,302,303 anybody have any ideas what it might be. The car is currently being flashed back to a stock setting after the original owner had Orton Perf flash it a couple of years ago. The new flash will be by Tony at Epl, he helped me with my other tt and it was great.

Misfire bank #i (cylinder 1-2-3). Can also be triggered by the vario cam. Take a good look at your valve solenoid bracket for the valve opening (3mm or 11mm). May be it is broken....

plus one.. those are all one bank kinda funny..
