'98 Explorer "Tune up" advice

Any help would be greatly appreciated! My '98 explorer XLT has 130K
miles, and I have only have one problem with it....a "chirp" that has
lasted about two months. Any advice? Also, what type of tune up should
be performed on this vehicle? Thanks much for the advice!

From a strictly maintenance point of view, I would suggest plugs, wires and
fuel filter - check or replace the PCV valve and air filters and clean the
sensing element in the MAF. A close inspection of all hoses and connections
(look for hoses that are rock hard, mushy or cracked).

i find that when my belt gets old i get some what of a chirp from under the
hood and a new belt fixes the problem and also never use bosch spark plugs
they caused me alot of trouble
