Maybe catylitic converter?

Hello, my jetta is running poorly. It starts fine but soon as one steps on the gas it bogs down until it stalls out. It is undriveable as is. when this occurs i noticed that it smells funny like sulphur.

Had the same problem with girlfriends 98 Jetta GL. Auto parts store told me OBD codes report multiple mis-fires so replaced plug wires, coil, rotor cap, plugs, etc. with no change in performance. Searched INET and other suggested throttle body or bang on CC and listen for rattles. Sure enough CC was melted down hunk of metal in there. Replaced it cheap $150 off Ebay and runs like a champ

Hi.
A sulphurous smell can be caused by an over-rich mixture or poor combustion sending unburned fuel to the catalytic converter.

I would suggest getting a fault-code readout which might start to point you towards the cause of the problem. Sorry I cannot be more specific, but all you really need to know is that you are requiring the services of a VW engineer !
Good Luck, D.

When the car is ideling, it runs fine. as soon as i give it gas it bogs out and stalls. it seems like its not getting gas. we tried the fuel filter. nobody thinks it is the fuel pump. what is the problem?


sounds like the computer is in limp home mode. Take it to auto zone or something and have them read the codes and then reset the computer or you can try to disconnect the battery for awhile and see if that will reset it.

I had a similar problem and the mechanic diagnosed it as a problem with the ignition coil. So you might want to get that checked.

Don't know if it applies to your diesel but most later gas engined vehicles have a 'cold start' valve that supplies additional fuel to the fuel/air mix along with boosting the idle speed until some warming of the engine is sensed.
