Hi all..
I am new comer on this forum and i have aveo 2003.
I have a problem that annoy me so much.
My engine rpm was unstable especially on idle and low rpm.
Sometimes it was normal and then suddenly increase and stay for a second in 2000 RPM.
I have try to replace the IAC and TPS sensor but didn't solve it..
Do you have any solution regarding this problem?
Thanks all for your answer..
