Jerks when going into 3rd or 4th drive.
Lincoln LS 2005. Car jerks into 3 or 4 th , automatic
transmission. Just got it and old owner said he changed 4
out of 6 spark plugs and coil packs but couldn't get to the
other 2. Could it be the 2 spark plugs that haven't been
changed? Or maybe a transmission issue? Also, had
some missing fuses, I changed them all but now my
battery is draining very quickly. Any thoughts or help is
appreciated!
