I re-checked all grounds. There are 3 straps in the engine compartment, Have good groung at the cluster and at the dash.So Now the only thing wrong is when I rev it the pressure goues down and after I let it idle and warm up it goes up. like almost 80 at an idle. Any other thoughts???? Should I just put the dash back together and order a new guage? Or let it be and put an aftermarket gauge in?? Maybe an aftermarket oil & water temp? Or oil and trans?? I'm getting a little (ok alot)
