I would try checking the spark plug wires, spark plugs, cap and rotor. I would consider replacing these if they are original. You might need a distributor. This this what is connected to the cap and rotor. This supplies the spark to the wires. I had a similar problem with a 94 aspire. It would hesitate when the gas pedal was pressed down and inconsistently stall when going in reverse after going on the freeway.
To change the spark plug wires on a 97 Buick LeSabre, first pull the wires loose from the plugs. After these are removed, pull the wires loose from the opposite end and replace them.
Could be in need of a tune up. Start with replacing the spark plugs and spark plug wires.
No. the plug wires are made different and the spark plugs ae NOT the correct heat range.
Mounted on your valve cover is a box where your spark plug wires connect. This is the coil pack
Perhaps spark plug wires are porous (due to age) and need to be replaced
there are two follow the spark plug wires down they are mounted on or near the tranny
You may have the wires to the wrong plugs.
