how old is the car,looking at the picture you have supplied it looks like a 1990-91 model?.this engine and injection/fuel system was used in the citroen bx range.from what i can remember there is a small unit bolted to the drivers inner wing with a screw slot in it.this can be turned to lower the mixture.if the vehicle is fitted with a catalyst and lambda probe it will need to be checked with suitable diagnostic equipment.
the mixture adjester i belive is the one on the alu panel next to the battery! i have adjusted this and changed it it makes no differnce, yeah its a 1990!i have adjusted everythin its been to a garage on a gas analiser the whole time i adjusted it nothing changes i have also made sure all vacume hoses etc are clear and no leaks!
