Hello everybody!
i have an issue with my Volvo 940 2.3t 1991 (b230ft+) and I can not solve it, so maybe I will get lucky and will find any bright mind Over here.
So, the problem is as following: my Volvo is eating too rich mixture, way too rich. Smells like unburned fuel all the time, exhaust pipe is black as hell and spark plugs fools pretty quick. when accelerating, car tends to bog (with fresh spark plugs it accelerates as it should, but after like 100 km it gets worse and worse). So far I have checked maf sensor, lambda, throttle body, timing, spark, engine pressure, vacuum leaks and everything seem to be working fine. I am thinking about replacing fuel injectors, but I don't think that it could be the case.
Does anybody have any idea?
Thanks!
