'01 Tahoe with 213K miles. Dies when slowing to a stop, but only while the engine is warming up. At cold start, the engine is fine and I can drive out of my neighborhood (stopping at 3 different stop signs along the way). Then I can make it half a mile down the street where it will die when I stop at the next stop sign. The tachometer drops below 500 then the engine quits. At this point, the coolant temp gauge is in the 180 range. Most of the time it will start right back up, but sometimes I have to give it throttle to keep it from dying. Once the engine gets to running temp at just below the 210 mark, it runs with no problems. I have cleaned the throttle body and MAF sensor. I have replaced the spark plugs and the wires. EGR valve is new and alternator is new.
