Could somebody tell me how to turn up the tickover on a VR6 please.And what it should be. Now it is about 550rpm.
I think they should idle at about 650-700rpm. I would clean out the throttle body and check that the ISV is buzzing at idle. Clean out the ISV and its pipes also. If that does'nt cure your problem I would get the car connected to VAGCOM. Hope that helps.
