Greetings to all of you. This is my first post after i could not find anyone with this problem! I had and i still have a engine shaking on cold start problem. Was diagnosed by bad compression and the mechanic changed the hydraulic lifters, oil etc... Now the compression looks good and the car is a little more powerful. But the shaking on cold start remains, its not the same and it last for about 15-20 sec. (before it was 1-2min) Its kinda like there is a miss fire but i dont have any check engine light on or any other problems it does smell a bit from the exhaust... So i went on to look up the injectors... On cold sarts it looks about like this: After some time it goes to this: Do you guys think i have a problem with the injectors or could it be something else? Any advice is welcome! Update: the shaking goes away after the ticking start the engine starts to idle nice and there is no smell from the exhaust.
