2001 chevy suburban,idles rough,check engine light flashes ,after truck warm up light go off and stop idling rough


Get a computer scan for trouble codes to see if that points you towards the problem. Possibly an engine sensor is not working right till it is warmed up. You might also check the idle air control for proper operation when cold.

Check engine light on, vibration at idle


Generally, the problem is in the emissions or something that is affecting the effectiveness of the emissions, but other causes can trigger the light to come on, too. To determine the cause, the vehicle will need to be taken to AutoZone or a shop that has an OBD2 scanner, or for 1995 and earlier models, an OBD1 scanner, While a scanner will not give you the magic answer, it will give you a code that narrows down the problem area.
Some specific causes for the light to be on are:
Gas cap left off, not tightened, not installed correctly, or needs to be replaced.
02 sensor.
Engine misfire - error might clear itself after 3 complete warm-up cycles; not restarts, but warm-ups.
At start up for a bulb check - Should not stay on.

Car rough idling causes
misfiring engine is among the most common causes of a rough idle. You may notice your car idling roughly when it's in "Park" or when you're driving it and stop at a stoplight. A rough idle can be caused by damaged spark plugs or spark plug wires or a burned-out valve. It's important to address the cause as soon as possible to avoid potentially damaging the engine. Engine repairs are almost always expensive.

2002 accent stalls and has a rough idle


During rough idling, when the clutch is released due to high rpm of the engine, the engine may stalls. Another possible reason due to quick release of clutch pedals.

First tune the idling of the engine. Look for the cleaness of the air filter, Fuel lines are clear for free flow. Check the spark plugs for free from carbons and gaps are maintained correctly.

When slowing down the car change to appropriate gears and netural the gears when about to stop.
