To Replace or not to Replace ??????

[bvanfossen]

is it suggested to replace the O2 sensors and the plug wires on a vg30de w/ 100k miles? water pump, timming belt, & trans serviced @ 64k miles. it's comming up on 100k miles and i was wondering what would be best to do for it. it's in a '93 J30 .

thank the- thank the

Yes it is advised.

one or the other might not be totally needed. but will keep everything up to par to prevent other misc. issues
