Hi, I've got a 2000 VW Jetta 2.0L and the check engine light has been on for a year or so, and I just got them checked at an oil change and here is the list:
Po134 - 02 Sensor Ckt - no activity (bank 1 sensor 1)
P1128 - manufacturer controlled fuel and air metering
Po442 - Evap emission control system leak (small)
Po300 - Random/multiple cylinder misfire detected
Po301 - Cylinder 1 misfire detected
Po171 - System too lean (bank 1)
Po304 - Cylinder 4 misfire detected
Po302 - Cylinder 2 misfire detected
it has been getting poor gas milage and sometimes stutters at a stop light in drive. I've ordered an o2 sensor for before the catalytic converter. Looks like most of this could have been caused by a faulty one. Any idea if I am diagnosing it wrong. It is going in tomorrow to get the o2 sensor changed, so if you can reply asap, it would be great. Thanks a lot.
have the same problem?
