Hello there, I recently purchased a 1991 Volvo 940 Turbo and there's some sort of strong exhaust smell that quickly comes into the cabin of the car. It doesn't smell like oil or gas objectively, but it is a strong smell that seems RPM dependent. I haven't seen any smoke or soot coming out of the exhaust system. The car doesn't seem to be consuming oil or water, but fuel economy seems to be pretty bad compared to my last car ('03 Pontiac Vibe) even across a relative scale. It builds boost fine and has no issues keeping the boost up there even to 5500 rpm.
I did try searching for this issue elsewhere on the forum but did not find anything in my searches that correlated with what i'm experiencing. Any ideas, advice or help is appreciated; thank you!
