Question about 1994 Ford Thunderbird
I unplugged the mass air flow sensor and the car ran better! new plugs, new tps cleaned fuel injection system, still can not get rid of that skip!!!! help
Change your MAF sensor unplugging it runs it in open loop and will run better if your MAF is going bad. I would not drive around with it un plugged. A smell of gas could be caused by a cylinder misfire doesnt burn the fuel but still pumps into exhaust and then burns in the ctalytic converter which can make it HOT! Also brns your cat and o2 sensors up

Unplugging the mass airflow sensor may be ok to do just to get you back home,,but it is not wise to leave it unplugged,,because your engine control unit cant decide just how rich or lean to make the fuel mixture without it.
A smell of gasoline is usualy a sign of this.
