Hello everyone,

I have this problem with idling when the car is at proper working temperature once at the stop light it goes up and down and cant keep the steady idling. Maybe any one had a similar issue?

Please check the video so you could understand the issue.

1. What other electrics are you using at the time? I.e. are headlamps on?

   The reason i ask, is that if there is no load on the alternator, the battery charge electronics reduce the current to the battery. If your battery is in a poor or weak condition, this will affect idling.

2. Linked to above, switch on ac all your lights, high beam etc - if the idle settles, it looks like a dirty throttle flap/actuator

3. Check air filter - my anecdote to this is that i found a plastic crisp packet had somehow been sucked into the air filter housing!

4. Check if your throttle is clean, deposits build up on the air flap actuator, and there is a small bypass that allows air to flow when throttle input is at zero. Any dirt can foul this bypass hole and cause rough idling ( i assume when you are actually moving, you have no issues with jerking or rough acceleration or constant speed.

5. Clean (or more likely replace) the MAF(Mass airflow sensor)

Hi Chris and thanks for reply.

I have cleaned the throttle body but the issue still remains unfortunately...

The rough idling is only present when the car is warm and stationary on drive.

Not sure how to access the MAF sensor, seems like you need to remove the plastics under the windshield to access it?
