I bought a 1993 SSEi and it had a guage problem every thing works fine except the oil presure and temp gauges twitch I was told that it was the whole instrument cluster so i have replaced it with one out of anouther 93 SSEi now the fuel guage doesn't work and then it does and the oil presure temp and boost guage don't work for about 4-5 mins then they start working. what is wrong?
