Hi guys, yesterday i changed my injector seats and breather hose and noticed something weird with my bosch Idle control valve, it was buzzing randomly and flicking back and forward slightly and looked like it was struggling to open, the engine was cold and has not been started at that point, so was wondering if its normal, iv heard there just supposed to snap open on cold start?

cheers

Remove it and give it a clean, see if that does the trick

How does the car run once started? How does the valve act? I seem to remember my 2.3-16 doing tha same on a few occasions but always ran fine so I just ignored it lol.

Hi stwat, the car runs like s**t lol, on a mission to get it running for MOT, iv changed loads but still it does the chocking on accelerator when cold or hot, firing up the intake, changed the injector breather pipes the other day and thats when i noticed the idle valve flickering inside and buzzing at random times when key is at position 1 on the ignition.

I see. Have you done the usual checks on the OVP? Is the alternator giving a good charge?
