I Have A 91 Buick Century 3.3, It Recently Got Hot On Me And I Replaced The Water Pump And T-Stat. But I Notice The Fan Wasnt Working So I Wired It Up So It Would Turn On As Soon As The Car Started Up. The Issue Is Something Keeps Shorting Out The MAF I Took It To A Shop And Had It Changed Out But It Ended Up Getting Shorted Out Again And The Car Starts To Run Off Around Like 2000-2500 Rpms And Spit Out Black Smoke And Cutting Off. And I Was Wondering Does The Temp Sensor Or TPS Have Something To Do With This Because The Fan Would Work Sometimes But When The Car Warms Up Is When I Start Having These Problems.
