did it fail because of a code? if so, what was it? among other things,
you need it to know which of the two sensors present is out of spec.

personally, i'd do the ignition stuff first, then see if the sensors are
ok. use oem for cap and rotor, ngk or denso for plugs, and oem or ngk
for plug leads*. you should also check the valve lash at this mileage -
if it wasn't done at the last timing belt change.


* regarding plug leads, oem are generally good, but i've not had a lot
of luck with them at high mileage. the best overall quality and
performance are ngk coiled core leads. they're about double normal
price, but last forever and perform great.
