I have a VW Polo Classic, 1.6L.

Just recently it started to be slightly jerky when in idle and whilst driving. There is also a loss of power, a strong fuel smell, and sounding slightly like a VW beetle.

I am thinking it is either:

  1. Spark plugs
  2. Fuel Filter
  3. Fuel Pump

Can anyone lend some advice on how to determine the issue?

Other possible sources:

  • Vacuum Leak
  • Other Ignition item (Plug Wires, Distributer, etc.)
  • Really poor fuel
  • Air Filter Blocked
  • Exhaust Blockage

I would start with the spark plugs. Take them out and see if they can give any indication as to the true problem. See this answer for more info (While you have them out, replace them if you need to). Then start checking/replacing easy items like: Looking for disconnected hoses, checking the air filter, etc.

Thank you @jzd for the answer. I will start with the spark plugs and revert. –  lordg May 21 '11 at 9:14

IAC, if it's fuel injected.
