Had the 350z garaged over winter, need to get it back out now the suns come out. Come to service it this weekend with new plugs, engine/gearbox/diff oil, clutch fluid etc
Started up OK with a charge to the battery but now the idle drops every 30 seconds or so almost to a stall...
I've tried searching to find a reason and think it may be due to cleaning the throttle body whilst I had the air filter all off.
Im pretty sure i moved the butterfly valve manually but since seen this is a no no.
Can manually moving the butterfly valve cause this issue and how so?
