I had taken my car to Jiffy Lube for an oil change about a month ago and a couple days after the oil change the check engine light appeared and then soon after that the car started jolting when driving or shifting into gear. Took it to get a diagnostic test and this is what came up:
Misfire 1, 3, 4
O2 Sensor
B1 S2

What is going on?
Is this an expensive fix?

Hi and thanks for using 2CarPros. Com.

The misfire can be caused by several things. This is a tough call because a bad o2 sensor can cause ignition problems and ignition problems can cause the o2 sensor to react.

Since you have a code indicating the o2 sensor is bad, I think I would start there. However, they only made these vehicles with four cylinder engines, so I cannot give specific information until I am sure if it is a 1.8L or a 2.0L.

Please provide that information so I can better guide you.

Just so you have an idea on price, here is a break down. Please keep in mind, these are averages. I have no idea what the shop labor rate is where you go or how much they mark up parts. To determine the labor, multiply the hours I have provided by the hourly rate. Also, the parts prices are for original VW parts. Aftermarket parts are much cheaper.

1.8L
O2 sensor: 210.00
Labor: 0.7hr

Spark Plugs: 4@ $7.00
Labor: 1.4hr

2.0L

O2 sensor parts and labor same as above

Spark plugs: parts and labor same as above

If you are a DYI person, provide the engine size and I will give you directions for checking components as well as how to remove and replace.

Let me know,
