I have a VW POLO (6N2) - 1.4 (60Hk), from February 2000.

After the car was standing still for 2 days in a rural area close to a stream (damp environment), the car had issues with being idling. Even after the car was heated. This issue did not exist before. After a 20 minute drive, and 10 minutes of the car being turned off, when I start the car it works fine at idle.

In addition, it has a hard time increasing speed. When I accelerate normally the car sort of jumps and the speed is not increased.

I am bit unsure of what can cause these issues, searching around on the Internet has led me to:

  • Issues with water/condensation in the fuel/fuel-lines?

  • Issue with the power distributor for the spark plugs?

  • The wires from the power distributor to the spark plugs?

  • The spark plugs?

  • The air intake or air leak ?

I find it a bit strange and would like some pointers on where to start with troubleshooting the issue. :)


I did not locate the specific issue, but I purchased new spark plugs and Ignition coil and it ran smoothly again :) So do this if you ever have the issue!

  • Could you provide the year of your vehicle please? – DucatiKiller Dec 8 '15 at 9:30
  • @DucatiKiller just added it, it is from February 2000, when it was bought new. – JTIM Dec 8 '15 at 11:30
  • When the car is warmed up and idling, if you step on the gas to rev the engine do the rev's hang for a bit and then suddenly drop down to a rough or normal idle? – DucatiKiller Dec 8 '15 at 14:08
  • @DucatiKiller no, then it sounds and looks as normal. – JTIM Dec 8 '15 at 14:19

    Yes, that certainly adds a layer of painful difficulty on top of everything. Well, I would be interested in hearing about the solution if/when you find it. Please jam it up in here if you discover the root of it. Best of luck to you! – DucatiKiller Dec 17 '15 at 7:37
