Hi guys,
almost two weeks ago I've had a timing belt changed @ 105k by my mechanic and since then I'm experiencing big problem with it.

This is a thread I started but didn't get many answers.
At first there was one code: P0506 - Idle Control System RPM Lower Than Expected
And today he's checked it again and it shows P0102, P0108 and P0113.
Anyone has an idea what's really going on with my car? Because apparently my mechanic has no clue
Please help, I hope someone knows something more about it.

The first two codes refer to your mass air flow sensor, the one on your air snorkel just after the air filter. Check to see if its connected properly, corroded at the connector, or if the sensor needs cleaning. The second I believe is your Idle Air Control circuit.

I'd check the MAF sensor first, clear the codes and see if that fixes things. Good Luck!
