Engine Hunting

[NJ86]

Hi,

I am having intermittent problems with rough engine idle ( 800-1600rpm) at a stand still. Have cleaned the ISCV numerous times with varying effects. Cleaned again today and when electrical connection is disconnected engine dies, is this a faulty ISCV or throttle body etc etc???

Any advice gratefully received.

Thanks guys.

it could be an air leak in the PCV system, so check all the rubber pipes you can locate.
