Well, I took my Z to the local Nissan dealer to see what code was being sent. found out it was the ISC (idle speed control) tried to reset it twice and it didn't change anything..
Well, after taking a drive up to Z1 in Ga. had another look at it and found out that it was something that I did in the process of changing things out.. I cleaned my throttle body and that changed the position so, what happend was it couldnt find its sweet spot. I will take it to Nissan this week, it is due a service anyway and get the Z tech friend of mine to reset the throttle position..
