Hi ! Im the new one who buy that.. lemon.
By the way im from Quebec, that why my english suck.

Millenia look great, i love it. But since I bought it, that goddamn check engine light poped up and the car started to buck everytime the supercharge need to give power.
Code said p1526 / p1540
p1526 is ABV Selenoid Vent.. so i changed that part and ABV vaccum too.

Check engine disapeared 15 minute then he came back with new code.
Now it p0404 and p1540...
My car run great at start when the engine is cold, after 5-10 minute running he start to buck.

I supose that now i need to change ERG vent/vaccum selenoid.. all the vaccum line and the Tee ?... That annoying ;/
What else it going to be after this ?

And.. is there supose to be a power steering cooler or something like that in this car ?
If yes.. it's got by passed


By the way, what mean ECU ?
