There isnt really a mention on how often you should change your spark plugs some manufacturers say certain plugs are good for upto a certain mileage Check with your spark plug manufacturers recommendation on spark plug changing intervals
check the coil first with a spark plug tester. then go to the leads at your spark plugs if no spark at the coil change it. .if spark found at the coil but not at the leads at the spark plug. then check the distributor cap and the rotor arm clean the contacts then check the plugs smell them of fuel if that is found change the spark plugs.
CHANGE SPARK PLUGS.YOU NEED SPARK PLUG 3/8 SOCKET.YOU NEED SHORT AND LONG 3/8 EXTENSIONS.YOU NEED SPARK PLUG BOOT PULLER AND A SPARK PLUG GAUGE SET THE SPARK PLUG GAP.NOW CHANGE 1 SPARK PLUG AT A TIME SO YOU MIX THEM UP GET FIRING ORDER MIX UP CAR BACK FIRE WONT CRANK.ALSO CHANGE PLUG WIRES ALSO.
you will need
5/8 spark plug socket
3/8 extension (it could be 4in and longer)
and spark plugs factory plugs are pregap iridium
spark plug torque is 13.0 lb.ft
coil torque 8.7 lbf.ft
spark plug part # NGK 1zfr5k-11
# DENSO pkj16dr-m11
and spark plug anti seize on spark plug thread
what you need to do is remove the plastic cover 8mm socket or 10mm sockets
now remove the spark plug covers and remove the spark plug coils too 10mm head bolt you will need a 5/8 spark plug socket and a 3/8 ratchet and a 3/8's extension too
you need OEM spark plugs they work the best
hope this will help
