Q: I have a starting problem on 2001 Volkswagen Cabrio

I replaced the air mass, coolant sensor coil, wires .Car will start and run sometimes. I seem to have an erratic weak spark. What else besides the coil will cause this thanks tom

VW is known for coil problems. Are there any codes in the computer? I have also seen a few computer reflash TSB's from factory. Sorry it is tough to say without some diagnostic information. If you can bring it in, I am sure we can help. Thanks, Scott
Could be a fuel pump, need to check for correct pressure. but could also be a mass air flow sensor, did you install new or reman?
My car is doing the same thing. I was told to replace the mass air flow sensor but haven't done it yet. Since it didn't work for you I don't think that was my problem. Did changing the fuel pump work?
