Low revs up to 20 vw polo classic 1.6i - Polo Volkswagen Cars & Trucks

SOURCE: VW Polo Classic 1997 IDLE Problems

Hello, VW polos 1.0, 1.4. 1.6, suffer from carbon bulid up in the throttle bodys causing bad idling, esp the Bosch Mono-Motronic (Throttle Body Injection systems), a good clean with carb cleaner should repair the problem, also engine temp sensor replacement and idle speed control valve replacement can help idle problems.

I have changed a few cylinder heads under warranty for this type of problem. The exhaust valve guides wear, this causes the exhaust valve to seat badly, giving low compression. if one cylinder compresion reading is more than about 50 psi below the others, then this warrants head removal. It is quite a job, due to the fact that the camshft id chain driven. If you are up for it then once the head is removed, poor liquid into the exhaust ports and see if it leaks out through any of the exhaust valves.

Has the car been serviced recently?
If not I would suggest getting it done.Not sure if you have diesel or petrol, but oil can thicken causing more load on the motor and airfilters get blocked and can cause a rich fuel mixture.

If petrol you can take out the plugs to check if they are a light brown colour, if very dark or black you need to check and adjust carb/injection settings/filter.Need to know what engine it is really.
