Okay, so check this out... my parents bought a beater 94 3.8 Tbird and it doesnt run to well... My dads old school so to chech if it need a tune up he sprayed under the hood while the engine was running. Okay so for the wierd part, It made it run smooth and evern made the check engine light go off. Another crazy thing is fan only works when it not plugged in... And when its not plugged in it wont stop. This car is just Crazy. Anybody ever have anything of this sort happen before.
