2000 Chev S-10 4.3L 6 cylinder

mass airflow meters should not affect idling of engine ,,, if they are faulty the power will be reduced or acceleration will be poor ,,,, it seems as if you have a idling issue or a tick over problem ,,, firstly check the throttle body for dirt and make sure there are no airleaks in that area ,,,,

You installed a new Mass Airflow sensor and still runs poorly, then it sounds like the computer is messed up (ECU). First try to unhook the negative battery cable for a couple minutes, and plug the new airflow sensor in, reconnect battery terminal and let it run for a couple minutes with the part in. It can reset the ECU.

I have the same problem few days ago, and still didn't find any solution. Can any one please help?????

Your only problem friend, is the temperature sending unit/sensor. Upon cold start, this sensor wil tell the computer to go into cold start mode putting a bit more fuel in and raising the idle a bit to keep it running when cold without using the throttle. Replace that sensor and your good to go. Makes sense, right?

sounds like a coil pack going back ....they work ok while cold but once it gets hot it stops putting spark out causing car or truck to stumble and stall and not start back up till it cools back down. Or it could be a bad fuel injector either clogged which would cause a lean cond. that would also make engine temp. higher then normal that over time will burn out a cat. converter which will choke the engine also or leaking tip which would make for poor gas mileage -rich, gas mixture and also cause a soot-black looking exhaust ,to check if cat. is back you can simply unhook exhaust before it reaches the cat and see if it will stay running then if it does then the cat is melted down -bad and need replaced if not something else like stated above is your problem.

this is a common problem for these cars glow plugs go bad like spark plugs however the smoke would lead to bad mass airflow meter. it is not telling ecu corrcet miss. disconnect mass airflow meter. when cold see if this makes it start better. it should would means you need new m.a.f. glow plug issue take a test light place clamp on positive of battery then pull off glow plug connectors place tip of test light on glow plug the bad one will have a dull light unlike the good one which will be brighter. will need new plugs and wire harness four **** connectors and wire striper and crimper will fix concern good luck

Thats the mass air flow meter.Should get changed at 60.000 miles. Also change the air filter.

The fuel pump relay will cause a stalling or no start condition. You are likely having mass airflow sensor, fuel pump, or fuel pressure regulator issues.
