Guys......I have a 1992 Firebird with 305 TBI engine,700 R4 Trans/Automatic with OD...... the problem I am experiencing is my tach is fine until it reaches the 3000 mark and then it wont go any further....No matter how much faster I go with the car the "Tachometer" will not go any further beyond that point, I know I have an electric guage cluster in my car and have already swapped clusters out to see if it happens to another one and it does the same thing also to the swapped out one.........I am really stumped with this one and would appreciate any advise I could get on fixing it.......

 

Does anyone want to give this one a shot.........this tach is crazzzzzyyyyy......ttt
