When I start the car and let it warm up the tach is off by about 600 rpm, says it is idling at 200 rpm. The speedometer sits below the the zero at a dead stop and appears to be off by about 10 to 12 mph while driving. What could be the problem. This is my first lexus, I bought it for 2500 dollars and it has 75,000 miles. Please help.

took cluster out and fiddled with the needles and now the tach and the speedo are perfect no problems whatsoever. my brake pedal feels spongy the fluid is a little dirty and it feels like I have to push harder than normal I heard this is common with 1990 ls 400. Also there is no needle for the speedo to lean on at a stop
