Having problems with your 1991 Volvo 940 ?
Turbo problems... I have a couple questions...I have a 91 volvo 940se with 118,000 miles....First off here is what i've replaced...cap, rotor, wires, plugs, fuel/air filters, first and secondary fuel pumps, oxygen sensor, carrier bearing, and bushing.... i've done a few other repairs but don't relate to my problem....My 940 SE runs pretty awesome for the most part, I had some plugged injectors wich was making the car miss fire at low level rpms....thats all cleared out but I am getting lambda co
These sound like the classic Ethanol problems I was getting, keep using it in that model and it'll start stalling too!! For some reason the ethanol doesn't go well with our o2 sensor, cakes it with carbon from the alcohol, I poured a bottle of octane booster and filled up with non-ethanol and haven't had the problem since
