As for the failure, it is usually the IAC or the TPS. IAC = minimum step -step motor and the TPS = Butterfly position sensor. But Eye is not just changing them, it is a matter of verifying voltages and checking sensors and lasts the computer.

On the other hand it can be air entrance, apply water above the multiple of admission if it feels that being on the car tries to turn off is an air inlet.

Verify that there is no additional air income, if that occurs the reling valve produces that variation, it also verifies the synchronization points in the distribution band just in case a tooth has not been skipped, also check the ignition time .... comment how it went ...

Hi, Mayck, I had the same car and with exactly the same problem.
The first thing I checked was the motor step by step, and it was not that.
Then, I went for the injector: we checked, we clean, measure; It wasn't that.
Finally, the problem was in the potentiometer (position sensor) of the butterfly box.
For the same wear, he begins to send erroneous information to the calculator, and begins to badly moderate the engine.
I hope this info serves you. Luck!

Look at there is no air admission hose that is broken or loose since that causes instability in that lucky vehicle
