Every week or 10 days i end up throwing a code i get p-300 which is multiple misfire (not all that uncommon) and p-175 which reads out too rich. I cant understand this one because if anything, i am running lean. Only thing i can think of is sometimes i give it some gas to turnover. Anyone else ever get 175?
thanks
