I HAVE A 1998 BLLAZER 4X4 IT HAS ABOUT 40,000 ON A NEW MOTOR WITH NEW WATER PUMP HOSES RADIATOR ETC U NAME IT ITS BEEN REPLACED OIL COOLING LINES REPLACED TWICE. ALL OF A SUDDEN WHEN I SIT STILL IT IDLES FIEN BUT ALL OF A SUDDEN THE GAUGES SLIGHTYL GO DOWN AND IT ACTS LIKE IT WANT TO ALMOST CUT OFF. THIS HAPPENS FOR ABOUT 2 SECS THEN IT IDLES AGAIN FINE .IT ONLY HAPPENS WHEN STOPPED AT STOP LIGHTS OR SITTING STILL. IT MAY HAPPEN SEVERAL TIMES WHILE WAITING FOR A LIGHT TO TURN. OX SENSOR REPLACE . THERE ISNT MUCH I HAVENT REPLACES. ANY SUGGESTIONS ON WHERE TO START. I DID HAVE A OIL LEAK WITH THE COOLER LINES WEEKS AGO SINCE THEN THE BELT WAS SQUEELING. COULD THIS BE AN ISSUE ?? WITH THE IDLE ??

do you have a check engine light on
if so get the codes
check it for tune up check cap and wires
also check for vacuum leak and the EGR valve
