just bought a 91 rs convertible today and I am having a issue with the gauges the speedo bounces and is slow the tach acts like its set on 4 cyl. fuel gauge is off and the temp gauge seamed to be right but the gauge shows almost 260 before fan comes on but with my temp gun it shows the motor to be about 220 when the fan comes on oil and volt gauges seam to work fine any info would be greatly appreciated thanks:feedback:

Checkout TGO, no insight here.

Fuck TGO right now, until they pull their heads from their asses.

Sounds to me like someone did an engine swap, and didn't change any of the components.
