HELLO, I HAVE A 1987 OLDS CALAIS 3.0LTR V-6 WHEN I START UP THE CAR IT
RUNS VERY FAST FROM 1000 RPM TO 2500 RPM WITH AN ERRATIC IDLE GOING UP
AND DOWN,THE ENGINE LIGHT COMES ON FOR A FEW SECONDS THEN GOES OUT
AND COMES BACK ON, SOMETIMES IT STAYS ON, IF I LET THE CAR UNTIL IT
WARMS UP AND REACHES HALF WAY ON THE TEMP GUAGE IT WILL STALL AND DIE
AND WILL NOT RESTART,IF I LET IT COOL DOWN FOR QUITE AWHILE IT
SOMETIMES RESTARTS BUT MOST TIMES IT DOESNT,I HAVE TRIED A PORTABLE
CODE READER TO TRY AND SEE WHAT CODES I GET ,BUT GET NONE ALL I GET IS
SERVICE ENGINE LIGHT COMES TWO QUICK FLASHES AND A PAUSE THEN ONE MORE
QUICK FLASH, I HAVE TRIED DISCONECTING THE BATTERY TO RESET THE
COMPUTER BUT IT NEVER CHANGES DOES THE SAME THING, ANYBODY THAT
COULD SHED SOME LIGHT ON THIS I WOULD BE VERY GREATFUL THANKS VERY
MUCH IN ADVANCE,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,JAMES
