My 2002 ford explorer is all of the sudden having starting problems. It will start, however often times if it is cold it will idle rough for about 10-15 seconds before it will idle normal. Never stalls, just has trouble starting and running at first. The car has about 91,000 miles on it and except for flud changes to the engine and transmission, and a belt and pully change, the car has had not major engine services done.
Any ideas as to what could be causing this?

i had the same thing, and i changed the fuel filter, it's located under the driver side by the back wheel, also after you change that add a bottle of fuel injector cleaner, remember to change your oil every season, 4 times a year, when you change the air cleaner , suck out the dirt in the box.

O.ok.- shall we initiate user-friendly. first of all, once you turn the main to the "run" place, does the verify engine easy easy up then flow out after some seconds? If it does then which ability no person bumped off the bulb to conceal a concern. in case you had a lean venture(inclusive of a vacuum leak) the PCM(powertrain administration module) might hit upon it and set a no longer hassle-free fault code and kick on the easy. an identical for a too wealthy venture. in case you had a misfiring cylinder (plug,cord,coilpack,etc.) the PCM might set a code for it additionally. genuinely, if the MIL (malfunction indicator or "verify engine" lamp) isn't lit then the region is probable an hassle-free one. i might propose cleansing the throttlebody. do away with the air inlet duct and applying an previous toothbrush/scotchbrite and carb purifier do away with all of the sludge buildup interior the bore and on the throttle plate. The IAC(idle air administration solenoid) is likewise yet another place to look. that's fixed on the intake with the help of the throttlebody. they regularly stick close inflicting low/tough idle. Have somebody turn the main on and stale. you will possibly desire to sense it "click" open and close in spite of if that's working. A gasoline gadget service is likewise something I tremendously propose. a clean gasoline clear out and a gasoline injector cleansing(with the device, no longer a bottle of snakeoil interior the tank!) is due with ninety,000 on it. A drippy injector no longer in basic terms drops gasoline economic gadget yet in addition supplies tough idle concerns. Did the hot plugs/wires help or exchange the idle venture in any respect? If no longer then that leaves gasoline,air,or inner engine(which i doubt). wish I helped. enable me comprehend the way it seems.
