Just want to thank everyone for their suggestions so far. I have purchased the TBI service kit (new gaskets, etc.) because I just wanted to see what was inside these units and make sure they were as they should be since I bought the car used with several thousand miles. Anyway during this process I noticed that the fuel regulator on the rear TBI unit (drivers side) has a small threaded bolt which is used to adjust the position of the spring. Well since I did not know exactly what I was doing I accidently turned this adjustment bolt and now don't know where to reset it. The instructions that came with the rebuild kit says this is set at the factory and not to mess with it. Does anyone know what I am talking about and how I can reset this adjustment? If so I would be most appreciative for any help. - See more at: http://www.corvetteactioncenter.com...corvette-warm-start.html#sthash.HFNekyJ3.dpuf
