is there any way a mass air flow sensor could be bad and not throw a cel i cleaned mine yesterday cuz the cars just seemed it didnt have any acceleration i think it made it worse any opinion i would be really grateful....
It could be a number of things really. I would go ahead and pull codes since it's free....there could still be codes logged even though the cel is not on.
a while back my car was running mad slow so i installed a new MAF and it felt like a totally new car. Never threw any codes, I didn't try cleaning it either tho.
