Carrera 2 2000 coupe 6 speed: tapping noise and irregular idle


Recommended Posts

There is a tapping noise in my car that appears to come from the idle purge valve, just above the alternator. The noise is not on all the time. It happens more frequently when the engine is warm. My mechanic removed the valve, cleaned it and reinstalled it. But the tapping noise did not go away.

I have also an irregular idle that may be related to the problem that is causing the tapping noise. Also the irregular idle happens prevalently when the engine is warm. I cleaned MAF and throttle body without achieving any improvements. I am aware of the possibility of vacuum leaks and low fuel pressure causing the irregular idle, but I would like to look into that after taking care of the tapping noise.

Any help will be appreciated. Thanks

Any chance you can get a video of what you are describing and post it for us to review?

I tried to attach a video file, recorded using my Nikon camera, to my reply to you, but I got a message stating: Error You aren't permitted to upload this kind of file. The size of the file is 4.18 megabytes. Any idea about what the problem could be?

Thanks

You may need a new valve. A slight ticking noise is normal though. I remember seeing others replaced that valve because the clicking is too loud.

I can live with the noise, but by my concern is the not properly working idle purge valve could be the reason for the irregular idle.

Thanks

Agreed and the valve is not too expensive if memory serves.
