Hello I have galant vr4 all stock accept for the turbo its a 16g running 10psi. Today the check engine light came on and the car started loosing power like running out of gas. At idle it sits at 1200 with a/c off and smells like raw gas from tail pipe ....after I bought it I noticed there was an safc2 hooked up to it,it could just be bad plugs but I don't know what the prev. Owner may have done , qs is if I unplug the safc2 will settings go back to stock .....keep in mind I have no idea if it was ever messed with ..... also a side note when I checked the oil I noticed it was just a little over full ... and. As for. Turbo I turned it down to like 3psi and still acts this way any help would be great thanks....
