Hello! I pray that you can help me. I have a 1999 VW Jetta GLS 2.0 4dr Sedan Manual shift. The new body style. I'm having difficulties with it. My check engine light came on so I pulled into an autozone had a scan and said o2 sensors needed replaced. So I get back home to ck repair shops and the car sounded terrible. Now it has lots of hesitation, it spits and sputters, engine rattles violently. After a start u have to feather the pedal to keep it running. Can you help me please :cry:

Did the code read lean bk1 and 2? Sounds like the Mass AIrflow Sensor. It controls the mixture according to the amount of air entering the engine

Did it run worse after auto zone touched it? Also try a fuel pressure test to make sure the fuel pump is good.

I've got a 2000 jetta 2.0 and the check engine light had been on for a while and never really checked it. When I had it checked, there was 8 codes, ranging from on output from o2 sensor, to air to fuel mixture wrong, to lean mixture, and to 3 different cylinder misfires. Keep in mind, these had been accruing for like a year. So I had the o2 sensor replaced two days ago, and it has been running like a champ, better gas milage and no light. My car didn't run as poorly as you said, just some hesitation, lack of power, and poor gas milage, so it might be more than that for you. But if you do have to get an o2 sensor. Get it from NAPA or napaonline. Com. I looked everywhere for o2 sensors, and they wanted around $100, in not more. I got mine for $44, same EXACT part as the others who wanted $100 like autozone, advance auto, vip, etc. Bosch, and it wasn't universal, it had the connector and everything. Saved myself $50 easy there, so check there first, i've noticed lots of times their parts are cheaper.
