So, If I will not fix my all problem, what is going on my car?
The engine problem is serious? After 7 months, I have to go back my country so, I think if these problems are not make serious accident, I don't need to fix it.
and this "have diagnostic codes checked which can be done at your local parts store for free but this will only be related to the check engine light" service is free?? and parts store mean mechanic repair shop or just auto part store??
yes, run is well. I'm worrying about unexpected problems like stop on highway.
If run isn't good, how can I know about it?? The sound? can you explain it with simple situation?? In my personal opinion, car runs good, but mechanic's standard is different. you have lots of experience about car.
