Hello good night, I have a problem with my Subaru Legacy B4 2003 Twin Turbo with Motor EJ20.
It turns out that today began to fail as follows, every time I try to change a march, whether RPM goes to the clouds, example if I put the second march the RPM are located in 3000, if I change to third march they go to 5000 and in the fourth march they go to 6000 ... All this without pressing the accelerator, is only when changing the march stepping on anything more than drunk.
It also happens that when I'm going to stop in a corner, drunken floor and brake, and when changing to the first march or second the same thing happens again, the rpm go to the clouds without even stepped on something in accelerator. This is stuck by a couple of seconds and then stabilizes.
It is also stabilized at the time I press the accelerator.
What can be happening ???
In advance, thanks.
Note: My father told me "I was testing some buttons located in the left sector near the driver's door, perhaps it is coincidence but after that I also noticed that the RPM were unstable"
