Bad idle, Rpm unstable
What cause this problem ? Idle move from 600 rpm to 1100 and drop to 400 and back to 1000 non stop. ?
All explain are approximative value.
The model is Mazda protege 2002, 2.0 Lit
The ODB read a alarm code miss fire.
Some people think that could be a timing belt problem
The mileage is around 109 k km
Thank you in advance
