Toyota Repair: 96 Avalon, coil pack, lifetime warranty

Question
I really have 2 questions.
1) Are the struts on a 96' Avalon guaranteed for life, if so,even if you are the 2nd owner?
2) I recently scanned for error codes and got "Multiple
misfires on cylinder 3 and cylinder 6.  Logic would dictate
that one would change the plugs and plug wires on those 2 cylinders....or is it a computer error?
Any help would be greatly appreciated...Thanks

Answer
Toyota does not have a lifetime warranty on the struts, the warranty period is for 3yrs/36,000 miles. This engine fires six spark plugs with three coil packs which are located on cylinder bank 2, this is the one near the radiator, cylinders 3+6 are both fired from the #6 coil pack, this is the one in the front valve cover to the right, replace this coil pack to fix this problem. Replace the spark plugs as well.
