I just got a 86 na seven and its having idle problems I started a thread in 2 gen sections with lots of response I tried setting idle but it proved to be harder than I thought. Is there anyone in Calgary that wouldnt mind giving me a hand properly as I'm new to this Fc. Would prefer to learn how to do it myself rather than paying a shop to do this as I will prolly have to do it again at some point but would prefer someone to show me in the right direction?
