Check Engine Light On: VW Jetta GLS


Approximately two weeks ago, a friend of mine gave me an automatic 1999 Volkswagen jetta GLS (4th generation). The engine this vehicle has is a 2.0 L four cylinder. The current millage is 89,000 miles.

Before taking the car to a dealer and spending $200 on a diagnosis, I would like to know if any of the users of this blog has suggestions to the following problems this jetta has:

1. While the engine is running and the brake pedal is depressed at a stop light, the engine; and therefore, the car vibrate. It is a kind of vibration lawn tractor engines produce.

2. When the car is being accelerated very slowly and the transmission shifts from first to second and from second to third gears, the transmission "kicks." However, if the vehicle is accelerated at a higher rate, the transmission makes the changes very smoothly.

3. While the car is running and the gas pedal is depressed between 45 and 60 miles per hour, strong and continous movements occur. It feels like the engine is shaking. The greater the acceleration between these speeds, the stronger the shaking.

Additional info: The car has the following codes,

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

In addition, the vehicle has a damaged cv boot and the vacum pipe has been recently replaced.

Any suggestions to fix the previously stated problems will be greatly appreciated.

Oh my, I have a 2000 VW Jetta 2.0 GL, and not even joking, I had those same exact 8 codes come up, no more, no less, those same exact codes. So, what I did was replace the oxygen sensor, the one before the converter, as it is the one that came up on the code, and I have traveled over 1000 miles and it has been more than a month, everything fine and no check engine light. Also, if you have noticed, the o2 sensors can be very pricy, but I found that on www. Napaonline. Com, for some reason, the oxygen sensor that fits this one is quite cheap, like $45, and everywhere else it is over $100. I believe the part number is a Bosch, 16121. Hope this helps, let me know.
