Problems
My 92 vette is not running right. The speedometer does not work, the check engine light is on, and the rev limiter acts like it kicks on a 3,000 RPM. This all started happening at the same time so I think they are related. I have taken it to two shops that do not want to work on it because the computer is not communicating with their diagnostic equipment. The car has an aftermarket security system and different cams in the engine. I also just had the battery and starter replaced. Anyone have ideas of what is wrong?

See this link to pull the codes yourself using only a paper clip:

For best results troubleshooting follow the flow charts in the correct factory service manual for your car, the codes do NOT indicate a part is bad, only that there is a problem in that electrical circuit. Many issues are due to poor electrical connections and do not require part replacement, good luck.
