Hello

I have problem with my Focus mk2fl 2009. It's 1.4 petrol. After night when I start up revs falling down to 500rpm and rev back to proper revs.
That happen only onece during cold star. Another start up will be ok. I have changed sparks, cables, coil, MAP sensor, throttle, injectors, fuel pressure regulator near the injectors. In the FORSCAN no error. Car work perfectly fine except revs during start after night...
Maybe you can help me. I wrote in english because I don't want to use translator...

Air temperature sensor and cool temperature sensor are ok. I also thought that problem can be with fuel pressure but I don't have manometer to measure. I will add that after changing the fuel pressure regulator for 2 weeks everything was ok but now it's again wrong...I wrote beacuse maybe somebody had that problem...
