Hi all, almost got this little bug sorted. Since I got it for her the CEL has been on and its throwing codes P0172 and P1128. The exhaust smells extremely rich, and I cleaned the MAF. Please point me in the right direction on this thing. I don't want to go slinging parts at it because there's a big list of whta it could be, from a leaking injector to a bad o2 sensor.
