Thanks for replies.

MAF cleaned, intake air temp sensor and throttle body flap cleaned also but didn't make a difference. BTW the engine starts perfectly, no matter hot or cold.

The fuel pump makes the usual "hissing" sound, can be heard around right rear wheel. The car develops some pressure in fuel tank but I guess that's normal.

I haven't been able to read fault codes yet, but I'm looking into that. Is there a way to read codes without special equipment?
