So thanks everyone for help. I finally solved the mystery. The issues with "hesitation" was a god damm valve cover gasket I noticed that drivers side was leaking quite a bit.. So i decided to change that gasket but when i removed both covers i also checked valve clearence which was bad.. so i did the valve adjustment then replaced the gasket on drivers side. When i put that back together it was a brand new car for a week or so.. then the hesitation was back. So i also did the passenger's side and and hesitation is gone and its all fine now. The second problem was just my stupidity, it was cuz of bad battery.. when i got the car i checked the battery and it seemed fine.. it had like 12.4V i think and the starter was rotating fine i thought.. but i tried to measure the battery while starting and voltage has significally dropped with different battery there wasnt such a huge drop in voltage and car started right up even in very colt temperature. Perhabs this will help to someone..

Hello, today i tried to check the fuel pressure like u said and it seems all fine its within the range. no drops or something like that. I kinda forgot to mention that in that car there's also and LPG, the problem is that the LPG is not working atm. Service told me that all 4 injectors are bad and needs to be replaced + reducer. I didnt mention the lpg because i didnt think it would be somehow related to this issues.. Since it should run fine when the lpg is turned off right ?

Hi, damn awesome idea. I'll try to get the fuel pressure gauge and check that out.

When i replaced the pump i tried to clean that sock with air and brake cleaner. I guess i can try to remove the sock and see what happens

Well thank you for your response. The problem is that if it wont be the pump then i spend fortune on that without fixing anything. Those NGK are straight from subaru.

Hi, well i try checking that out. I guess there isn't possibility to clean that damper if its clogged or something right ?

I dont think the problem is in gasoline, my friend has a 2.0 121kw 2006 and runs fine and we tank on the same gas station. I live in Czech Republic. About the injectors i'm going to try liqui moly gasoline engine cleaner maybe it'll do something. Oil has been changed recently by me, but i think its not overfilled (i still check that out) engine did the same thing before with old oil even when low on oil.. I tried to change the fuel pump just the pump not the whole assembly and that "filter sock" i guess i can try to remove that sock if it gets better or not. But if it would be fuel pump it would have bigger problems when driving or at higher rpms it would work or not ? Because once u take off it runs all fine.. You can cruise slightly above idle and no shaking or something like that..

Hi, it's drive by wire. Throttle body has been cleaned, gasket is quite old so im waiting for new but i dont think there will be difference. I'm using Free SSM I also tried different crank sensor and no difference.. The problem is that if u build up rpms slowly its good.. but if u tap gas pedal fast there's a 1-2sec where it "chokes" then rpms go up.. I also guess long cold starts has something to do with this. I tried switching the key few times to build up pressure for the start but no difference. Once its warmed up starts all fine.

Hello guys, could someone help me with following issues ? When i try to start the car early in the morning in cold weather it takes like 10-15 sec, once its warmed it starts without problem. There's also a big flat spot when i try to smash gas pedal or when i try to accelerate from a stop. I've replaced maf sensor, cleaned map, new fuel pump, new spark plugs, previous owner replaced coil pack. Please does anyone have any idea what to look for ? Because atm i'm kinda desperate. adding link to video + live data

Thank you for advice.. I just couldn't find a useful wiring diagram for MK IV to check that out. All fuses checked and none of them bad. I guess I'll try to check hinges if wires are in good condition.

Well thank you for your help.. I'll check that out. I thought it's too much coincidence that both doors wont lock/unlock. You think that both would gone bad at the same time ? I just bought that car recently.. and previous owner told me that back doors never worked. So i thought that it's just a fuse/relay or coding problem..

Hello, does anyone had an issue when central locking system wouldn't unlock back doors ? I have 2 keys.. when i use remote control, it unlocks both front doors and trunk but won't unlock back doors. Same if i use arm rest control for unlocking, it opens only front and trunk Any ideas what could it be ? Thanks for any response..
