The only other issue I can think of would be electrical. As it sounds like you know what you are doing in regards to DIY mechanics, I would probably trace all the electrical lines even back to the ECM. Also I would try clearing all freeze frame and ECM data resetting it to factory spec. Has any other electrical issue cropped up? (Lights? Audio system? Power door/Windows?) The master switch under the hood may also need to be inspected and ensured that its properly grounded. When installing the new cluster did you ensure that the cables that drive the speede/tach are all connected and tensioned properly? I will monitor your post for a reply and hope this helps! Best of luck!
Yes I have diesected plug into back of cluster looks good .... I have not looked at the master switch under hood ?? But all other electrical is working as it should .. And vehicle runs and drives fine ...
