Question about 1987 Volkswagen Jetta
I own a VW Polo Classic and constantly experience IDLE problems. Please advise on problem and solution. Thanks
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.

Check your lambda sonda or sensors on fuel intake system

There might be a large build-up of Carbon in the Throttle Body. Around and Behind the Butterfly it
seems that the Polo suffers from this problem and is quite common.

If battery or throttle body has been removed the parameters on the computer that controls the idle step on the throttle body zero's out. In this case you will need to conduct a throttle body alignment via a vag based program using a generic vag compatible obd2 cable.
