I bought my car at an auction so I did not know anything about it or what it had been through. So when I picked it up no water in the reservoir tank. Found the leak in the coolant line replaced it did an oil change and flush the radiator and put new coolant in. The leak seemed to be fixed. So I drove it home and it was fine. The following day I drove it across town and on my way back home it started stalling out on me. Like I hit the gas and got no acceleration. I barely made it home, and parked it. A few days later I started it up and it seemed fine. I drove it to the parts store, and had them run diagnostics. Got code p0420 and was told it's either o2 sensor or bad catalytic converter. Then I was told by someone else that the o2 sensor would not cause my car to stall out. So I drove it again, and realized that when I got on it (took off at a fast rate, high rpm's) is when it started to stall out shortly thereafter. Same as the first time. Also the same day, my car told me to stop check coolant, engine was getting hot. Checked and there was nothing in the reservoir tank. I added coolant and temperature dropped and it seemed fine. I took it to O'reilly's again and had codes ran. This time they tell me constant misfire as well as I have a leak somewhere again on top of the p0420 catalyst system below efficiency bank one code. I use only premium, but not sure what previous owner used. I am at a loss of what to do, and scared to drive my car any sort of distance. What do I do? Spark plugs? O2 sensor? New catalytic converter? ($600.00 to $900.00). I am not familiar with Volkswagen's at all! I would like to fix it so I can sell it, but I do not know where to start and I keep getting all kinds of different suggestions from people, none matching.
have the same problem?
