Question about 2000 Volkswagen Jetta TDI
I have a 2000 VW Jetta 2.0L 4 cly. My mom handed it down to me. It has about 180K in miles. Me and my dad recently gave it a tune up and oil change. It ran fine for a while, but later started bucking. Then we put new spark plugs, spark plug wires, fuel filter, ignition coil, and a oversized plug for the oil pan, it was leaking oil. It was running good for 2 days and started acting up again. I found out my mom wasn't taking good care of it and drove it from RI to PA several times without giving it tune-ups and oil changes as needed. I took it to Auto Zone to check the engine light 8 codes came up. P0411, P0138, P0139, P0303, P0301, P0300, P1237, one of them I fixed myself. I planned on getting a O2 sensor but my mom said she put one in not to long ago but it has to be in there wrong. I'm pretty much feed up with it. Can you please tell me what you think I should do and what parts I may need to get to fix this problem, please. Thanks in Advance. Boss Lady
What Auto Zone doesn't do when it reads the stored DTCs is tell you the probable causes and what has to be repaired or replaced or retuned. You need to find a competent mechanic, not just a parts replacer, who will read the stored DTCs and determine what has to be done.

You are mis fireing on cyl 1 and 3 if you replaced plugs and wires and coil this is going to be a fuel injector issue or valve issue. See if you can swap the injectors with known good cyl. and see if it changes. Or have a shop do a fuel injector service on it to see if it helps. It may be to late for the fuel injector service.

Blinking engine lt. Poor performance-barely make it up a hill.
Mechanic said bad O2 sensor--Replaced--had same problem-
Used "ADVANCED AUTO" Diagnostic meter---FREE FREE FREE
Code read MISFIRE
Replaced COIL pack!!!!!!!!!
Returned to Advance auto to clear codes---
NO CHECK engine light --runs like new
Believe the COIL pack went bad causing the sensor to clog and go bad--Probably could have just cleaned it.
Cost $200 parts and free labor>LOTS of bad words,gerasy hands and good running car
HOPE THIS HELPS SOMEONE

The oil in the spark plug may cause the car to run sluggish. The oil may prevent the spark plug from firing correctly or cause you to burn oil. You may want to replace the oil seals around the spark plug holes by removing the valve cover and you should be able to change the oil seals underneath the cover. While at it check the engine for loose wire connections and loose vacuum hoses.
