I have a 2003 Lincoln that is jerking bad between gears. Hoping its not the transmission. tester said first cylinder (spark plug) as per parts store. would a bad spark plug make it jerk between gears.
Lincoln mechanic says there testers showed 02 censor bad. Napa showed cylinder 1 bad.
My automatic v8 jerks between gears, Hoping not the transmission. can a bad spark plug
make it jerk between gears while driving??
