It has the 4.0 engine at 160,000 miles. everytime i start it up it sounds like it wants to stall and will cut out for a second and then idles. anyone have any idea what could be making this act like that. Also when its idling it just will sound funny as it idles like it goes low then high like its gasping for air and just doesnt seem to idle right either any ideas

ya your engines shot, time for a crate.... haha just kidding.
seriously though, run some injector cleaner, change the air filter, clean the maf and iac, and change plugs/ wires if they are old, also you could clean the throttle body out a little.

my '99 Explorer Sport (Manual Transmission) does the same thing sometimes, so most of this information has been really helpfull, but what do maf & iac stand for? Sorry I'm a girl, I've learned how to change my own brakes, but there is SO much more for me to learn, also how do I know if it's OHV or OHC??

Mass air flow sensor and Idle air control,look on your vin # and it will tell you here http://www.explorerforum.com/ntrprize/VIN.htm what engine you have,get a Haynes manual from Advance of wherever to see the location of the above.

IAC stands for AIR IDLE CONTROL
MAF stands for MASS AIR FLOW
If you have a V6 it's either a SOHC (single Over Head Cam) or OHV (over head Valve)
Open the hood and check what it says on the plastic cover. Does it say SOHC?
If not, then it's an OHV
Another way is to check the 8th vin# if it's an E then it's the SOHC

Thank you everyone, that is very helpful, (will a tune up help at all?) I hope I can get back to this thread when I get home and can check since my ES is currently sitting in the garage with a snapped e-brake/foot brake (I am trying to find a post on here to find out if I can replace the cord or if I have to replace the whole mechanism as I've been told)
