p0171 and p0300 nightmare
well the jimmys been running great beside he odd little hint of a misfire... no codes thrown, except the fuel mileage didn't go back up.... looking at the reader my fuel trims are bouncing back n forth as the should and the 02s are still bouncing back n forth not to bad.... either or its running like a top....
new problem arose today as i was sitting at a light... i got a p0420 code... so i double check the 02 readings they still look normal...
