Question about 1991 Volvo 940
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
