Having some problems with my 96' Volvo 850. Recently changed spark plugs as well as fuel injectors to try and fix problem, didn't work.

Its reving up without me even touching the gas, and burning real rich. Its almost as if its reving up to try and keep itself going. Hooked up an obd scanner that said it was something to do with the mass air flow because of a high input. But i have no clue what i'd have to do to fix that. Also, my exhaust output is smelling like burnt gas.

I don't know if its because of a bad catalytic converter and I'm not getting enough air flow, the air flow sensor, bad o2 sensor or what. It's just running real rough at the moment.

Oh and that oil behind my car isn't from my vehicle, its from another p.o.s i have lol. But yeah i have no clue as to what the problem is or how to fix it. Anyone had a similar problem or some professional advice? I'd appreciate it much. Thank you.

 

sounds like a vacuum leak somewhere.
