i have a 91 gt. my tach does not work when i first start the car in the morning, or after it has sat for a couple of hours. it jumps to 3200 rpm and sits. but after an hour or so, it will start working fine. i am wondering if it is a problem with the tach itself, or does the problem originate somewhere else. but, while the tach is stuck, the engine still runs like everything is fine. also, there is a small melted spot right below the tach itself. so if anyone would have another tach laying around and wouldnt mind parting with for cheap, let me know. also, where can i get white face gauges?
