Hi,

My 1993 Pontiac Grand Am, quad 4, distributerless ignition, misses like crazy under load, it doesn't matter what speed or gear. It's better when cold but rapidly gets worse as car warms up. I've replaced the connectors but it made no difference. Could it be the coil pack?

Quad fours are known for plug towers and coils. Pull it and check for cracks.
