The Engine was just rebuilt in April and im using all New Silicone Hose. I check them often to make sure they dont split. I have had a couple do so already. Ill have to look for what your talking about Jerry, You Seem to know all when It comes to the Zu's. Other than that I runs Awsome and dont have any complaints, Other than I need MORE. I really can understand why that would Affect Fuel Mix. Rather Obvious at that still dont know why i over looked that HAHA. Is there any way to get the connections crossed by accident, Like maybe the connectors are the same?? But Im still curious as to what that little box looking thing is where I was describing. I want to get that fixed and taken care of.... and I really DONT want to take the intake plenum off again.. I had to take it off several weeks ago to fix the Injector seals and that was a VERY FUN JOB*. Ill take a look at it and see what I can come up with. Thanks for the Input guys. Very much appreciated.. another question: Is Isuzu shutting down due to poor sales or are they just producing what GM wants them too? I dont know but again Im curious...
