In reply to Carin Roberts. You'll probably have a check engine light for a bad MAP sensor. Have you checked the idle air control valve (IAC)? This is a possible cause. The IAC controls your idle as you turn accessories on and off, such as the headlights and air conditioning. Is the vehicle more likely to stall when you run the air conditioning?

In reply to arnaud. It's possible, but it sounds like you may have something else going on if pressing the throttle helps. Is it idling rough?

can an engine turn off while the car going because of a bad MAP?
My car has a probem. it turns off when i’m driving it and stops in the middle of the road. it takes over 10 mins to start again and i have to press the throttle.

In reply to nikki. It could be an issue with the throttle position sensor itself, or an issue with the wiring between the throttle position sensor and the ECU. If you are handy with a multimeter, the factory service manual should have more information on expected voltages from the throttle position sensor. You can test the sensor and the electrical connector for proper operation. If this type of diagnostic work is outside your comfort zone, it would probably be best to bring it by a shop to make sure the throttle position sensor is working correctly. It's not a component you want to ignore.

Car is a 58 plate 1.3cdti corsa it drives fine until hit 3000rpm the spanner light comes . Doesn’t in any gear go over 3000rpm just like sort of stops trying to go faster unless downhill will push a tiny bit more rpm out does this sound like a 02 sensor/boost sensor

In reply to James. This will likely depend on your specific vehicle. It would be best to purchase a factory repair manual that has a wiring diagram before diving into that type of troubleshooting. For some vehicles, these manuals can be found for free online.
