Consumer Description

HAD P0128 CODE FOR ABOUT 1 YEAR. REPLACED THERMOSTAT AFTER P1680 CODE, REDUCED ENGINE POWER LIGHT CAME ON. REDUCED ENGINE POWER LIGHT WENT AWAY ON NEXT CRANK UP TO MOVE VEHICLE AND CHANGE THERMOSTAT. ABS AND BRAKE LIGHTS BOTH ON INTERMITTENTLY. TACHOMETER HAS BEEN STICKING AND SPEEDOMETER SHOWED ERRATIC SIGNS AROUND 55 MPH. NOW ALL GAUGES GOING WACKO OR NOT WORKING AT ALL AT TIMES. TEMPERATURE GAUGE WRAPPED COMPLETELY AROUND WITHOUT EVEN STARTING COLD ENGINE. ABOUT A MILE LATER, INSTRUMENT PANEL LIT COMPLETELY UP THEN WENT AWAY, GAUGES RESET, AND RAN FINE WITH PROPERLY OPERATING INSTRUMENT PANEL... AT LEAST UNTIL I GOT HOME. THEN WACKO STUFF AGAIN. RESET PCM BY DISCONNECTING BATTERY CABLE, NOW THINGS SEEM FINE... FOR NOW. I'M TOLD TO REDO BAD GROUND ON ECBM BEFORE SUSPECTING BAD ABS MODULE AND TO REPLACE IGNITION SWITCH BEFORE SUSPECTING BAD INSTRUMENT CLUSTER AND PCM. HOWEVER, DEALER ANALYSIS SAID ABS MODULE GOT MOISTURE IN IT AND THE INSTRUMENT PANEL NEEDS TO BE REPLACE. FIRST IS A $1000 ABS MODULE, SECOND IS A $400 PANEL, BOTH HAVE LABOR CHARGES ADDITIONAL. *TR
