We flooded the old girl a week ago in the cold... after a few hours, got her going. Since then, she misses/stumbles/jerks going up hills and holding a constant speed around 50mph and higher.

She has the 3.5L motor and ran awesome before... any ideas where to look?

Plugs are 5 months old, wires 3.

Any assistance is appreciated... Cheers! :)
