DAEWOO LANOS 2000 1.5 Baja failure

Good morning gentlemen:
A couple of days ago my Daewoo Lanos has a small failure in low (idle) either with the hot or cold engine, the air and gas filter, the gasoline pump and the TPS (Throttle Position Sensor) change and add an additive in the fuel tank for the cleaning of injectors, but the probloem cables and coil ....... Someone can give me some suggestion ..........?

ERMO1 Do not tell us what is the problem you have in relief, it is an instability, it is based on a less smoke piston or what?

It does not make smoke, it feels like an instability that is accentuated when I turn on the A/A and sometimes in the semaforos the engine is turned off ....... what can be ....?

If the pressure of the rail is fine, take out spark plugs, put them in a dough and see what spark they have to have no intensity, if so change the coil again. If it carries flow cleaning it.

Hello,
the safest thing is that this dirty idle Teep Motor (step -by -step motor) is in charge of adjusting the amount of air in idle more with the air if the symptoms that it should have is tacometro is that the needle rises and lowers and does not compensate the other symptom is that when the decelerated Carburetor is very easy to get ... Then he reset the computer disconnecting the negative of your battery and test it ... that would be.
