KIA AVELLA Motor strength problem

Hello everyone:

Consult, I have a kia Avella from the year 99, I did a maintenance of the alternator, but after the mechanic gave me the engine, the engine above all in climb, I would like to know if someone can guide me in this problem

thank you

Greetings! It is sure that your mechanic had to disconnect the battery to get the alternator from your vehicle. When doing this, the learning data that it had stored in the RAM were erased and then when it connected it to the battery and light the engine the ECM starts its operation with all the initial adjustments of the manufacturer that may not be the ideals for the operation of the engine in the location in which you are ... the good thing is that the ECM of the car "learn" about the conditions in which it is currently working and it is a completely automatic process. My advice: Use your vehicle on a continuous trip of at least one hour trying to use all possible operation variations .... first locate it and let it arrive alone without accelerating or anything at the normal operating temperature then if you can do it at constant speed, motor brake, constant speed then overtaking ... the idea is that you take the engine to all kinds of situations that could occur in the normal conduction so that the ECM takes data and adapts the data. To your particular location after that should no longer have problems. I hope it helps you

Very good response Alge, what you say in Toyota vehicles is correct, the same thing happens, you will see how your problem is solved, of course if you have the media a diagnostic team can make it faster.

Actually, walking during this day the engine recovers power what if in idle all the car trembles as if it were a petroleum, you will have lost the setting? Because before it was accelerated and now the engine trembles, it hurts that I have no tacometro to compare

Greetings.
That is what actually happened ... ECM lost its (self -affination) the moment when the battery disconnected. For what you imply, it seems that I had not received appropriate information at all because I slowed down is unstable .... It would seem that possibly more training would need a little more training so that everything returns to normal. If possible take out the air filter and clean it or change it if possible. Even I would go beyond and I would also exchange the fuel filter so that the data that the ECM collects are more reliable to a refined motor situation so that it even reduces the fuel consumption a bit ... of course, that is what I would do but I believe in your case I would only handle it to handle it a little more. Try these ideas and let us know any evolution ... we are all here to learn. Greetings
