Pete, I couldn't find a vacuum leak this was my first thought I will pull the plenum and check. The Dorman plugs were used to cap the secondaries and I don't see them coming out but will also look at that. The port under has been capped. The TB was done by the PO all I did was refinish it and reinstall. Everything operates smoothly without any binding. I don't have a stock chip but I will pull the one off of my Z and see how that works or if it changes anything. Quote:
Scott, No codes are being thrown. I will try the IAC tonight and see what that gets me. Quote:
Yes, new O rings in the IH's (where needed) and on the injectors form FIC (where needed) had the O rings already installed so it is all new. Thank you for the tip I will give it a shot. Quote:
We did not port the TB just refinished it when Tommy Morrison had the car the TB was done this was in the late 90's. Thanks for all the advice guys we will see where this takes us. Daniel |

I don't know if it is the same problem as what I had, but I had my throttle body enlarged to 63mm and I assume new throttle blades were installed to fit the new sized bores.
Then later I had the throttle body powdercoated. Afterwards I experienced high idle. Mine would start off with normal idle until I drove it, but then after driving it would always idle high until I shut it off and restarted it. I was told that the baking of the throttle body in the powdercoating process that the bores might be now odd shaped from the blades. Made sense to me that heating of aluminum could make these openings change shape. I sent my throttle body to Marc Haibeck for rebuild and all is good now. Did you do the test Jim mentioned or the adjustment XfireZ51 suggested. If you don't have a vacuum leak, you might be experiencing what I did.

That makes sense but it seems to work just fine. The Z hasn't run long enough to heat up yet. I have not had a chance to try any of the tests I am still at work for a few more hours at the moment ![]() ![]() Daniel |

What do you mean by "refinished the TB"? Were the plates removed? Any part of the throttle mechanism touched?
