map sensor or something else?

[Apsogos]

We still havent find solution here.Cleaned the throttle body,changed the iscv,changed the water hoses on throttle body,setup the tps,checked the valve clearances,checked the compression,replaced the hoses behind the tvis ,we left on purpose the tvis butterflies open,the tvis valve works fine.Now i am waiting new temperature sensor and we will check the fuel system and another pressure regulator.

Ps i forgot ..we bled the cooling system.


the problem begins at the start of the engine at choke procedure as you can see on the video...nothing changed with the new iscv .

when the can is at operating temperature....the problem is that engine working like this: vououum - pop pop - vouuuuuum vououmm -pop pop pop -vouuummm

the engine should work only like : vouuuummm all the time "i mean stable"

the "pop" thing you can hear it from cold to hot .....nothing changing....
these changes can be seen at idle on the rpm indicator but are very very small
