Customer Question
Hi I have a 1994 vw...
Hi
I have a 1994 vw golf, 2.0i 8v.
The engine has started to rev up and down on its own when ticking over, sometimes it steadys to about 800 rpm but sometimes cuts out, when driving, it appears to be ok while driving when warm through the gears but when i come to a junction the engine can cut out or continue to rev up and down generally between 800 rpm & 2000 rpm.
i have change plugs, leads, cap, fuel dont know were to go next.
Does anyone out there have the answer or seen this before ???

Hi Sorry

i dont understand, "did i blled the top off the cooling system" ?? are you asking did i bleed the top off the cooling system, if so, this idle control valve is not connected to the cooling system ??

VW Mechanic: Cardoctor74, ASE Certified Technician replied 8 years ago
I undertstand that alot of times an air pocket in the cooling system can also cause this.
