ltft show a major vacuum leak, have you tested the PCV valve it should only work in one direction, why parts from Japan most parts are still available over here

Any possibility u can send me link where to buy from

It depends on what you require, many manufactures share parts across cars, usually I look up the OEM part number and go from there

Looks like if found that faulty ordering these

You don't need the hoses unless they are cracked or perished

It's probably gone into default to mode to keep the engine running, as in a limp home situation.

TBH, if you wish to carry on with self diagnosis your best time will be spent on Google, YouTube or maybe try one of the American sites as I don't think too many folk on here are diagnostic experts.

Update : after changing pcv I drove more then 100 miles No engine light came up and only one point down 😁 b4 it only take 20-30 miles to pop in on my dash looks like we got the culprit

Good news for your endeavours and a good call by Flash22 for suggesting the PCV👍
