Hello guys anther ??? About my jetta 2.0 i just fixed a misfire problem. But i got 3 codes p1128 p0134 p0112 could anybody give me guidance on what i should do first to fix this problem??? Uncle Scotty said i need to go back stock on my intake box cause when i bought the car it had that blue custom thing on the air filter like the race cars lol i bought the car like this but I'm trying to get rid of the codes any help would be great thanks
It may be impossible to fix if you don't go back to the stock box and sensors
Ok thank you uncle Scotty ima go to u pull it tomorrow and grab a stock air box to see if my fuel trims change i already got to change the fuel ratio sensor and the map sensor bad to i believe them codes are for them parts but ima go back stock tomorrow and see what she do wish me luck.
