RepairPal Certified shops can diagnose and repair your 1997 Buick LeSabre. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Update:
Engine stumbling, missing, lack of acceleration. When "flooring it", transmission hunts for gears due to engine stumbling. Got worse and received a P0303 code.
Bought plugs and plug wires. When removing plug wires, noticed rust on 2 of the coil "nipples" (for lack of a better word), #3 being one of them. Cleaned rust off coils with wire brush and sandpaper, installed new Bosch Iridium plugs and wires.
Cars runs like a swiss watch now. 105,000 miles.
Thank you for reply and help.
