Yes
Stay with your original thread, starting a 2nd thread is not a good way to get help.

My lacetti revs up in a strange way

I made a test with the maf sensor. While the car is at idle the manifold pressure that the sensor is reading was 50kpa and when i open the throttle the pressure dropped to 20 kpa almost.
