When i press on the gas peddle the car hesitates and jerks. If I do it slowly it doesn't do this... But, you can't press hard on the gas peddle or it will hesitate.

I think your car is runing Lean and i would say check the Mass air flow sensor and the fuel system because your car seems like its sucks more air then fuel. Do you have any check engine light on ?

1994 Buick Skylark. Lot of hesitation and jerking, power locks


HI MY NAME IS JUAN:
I HAVE A 93 BUICK SKYLARK CUSTOM
AND I HAD THE SAME HESITATION.
I CHAGED GAS FILTER, AIR FILTER, AND USE SEA FOME IN MY GAS TANK AND USE IT ALSO TO CLEAN THE INTAKE SYSTOM, AND IT HELPED ALOT. TWO MONTHS DOWN THE LINE HADE THE SAME HESITATION AND IT WAS ONE OF THE INISION COIAL PACK WAS NOT GIVING THE ELETRICAL SPARK TO THE PLUG. I CHECK IT BY PULLING THE CABLE OFF THE SPARK PLUG WITH THE CAR RUNNING AND FOUND THE ONE THAT WAS NOT GIVING SPARK. I REPLACED THE PACK FOR THAT CILINDERS PLUG AND THE PROBLEM WAS GONE.
HOPE THIS CAN HELP YOU.
