This sounds like a fuel problem the engine is starved of fuel, check your fuel pump clean the filter in the pump, It could even be that you will need to replace the fuel pump. Cheers, Malcolm Campbell.

Idles high and low

Although it could be any number of things you may want to start with the air filter, a dirty air filter restricts the airflow to the engine and can cause exactly what you have described.

3 other suspects could be, Idle air control valve, mass airflow sensor, or throttle position sensor.

2007 crown vic 4.6 l idles high on startup

This sounds like a normal condition.What happens is the cold start emission reduction component monitor(software program in the computer) is running.
Cold Start Emission Reduction Component Monitor
The Cold Start Emission Reduction Component Monitor was introduced for the 2006 MY on vehicles that meet the
LEV-II emission standards. The monitor works by validating the operation of the components of the system
required to achieve the cold start emission reduction strategy, namely retarded spark timing and elevated idle
When the CSER strategy is enabled, the idle air control system will request a higher idle rpm, elevating engine
airflow. While this CSER elevated airflow is requested, the low airflow test compares the measured idle airflow from
the MAF sensor to the commanded idle airflow from the idle air control strategy.

1992 VW Polo 1.3L Coupe: warning light mystery

Bought a very reputable diy service manual for the vehicle, and that plus a bit of thought and nous gave me the cure: no intrinsic problem other than loose relay connections. Went round with the wiring diagrams as guide checking all electrical connections in tight and relays fuses etc all good. Switched on and no problem any more.

By the way, vehicle is 1992 VW Polo - not Fox (which in UK is a variant of the Polo)

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.
