99' Ford Explorer starting issues ?

My Explorer will only start when I have the gas pressed and when I let the gas go it shuts off can someone help please?

Sounds like a vacuum leak. Check the vacuum lines for crack's and make sure the line's are connected. When it run's is the check engine light on?

no lights, just wont start unless I give it gas, and the only way it will stay running is if I keep giving it gas, I let go It dies ?????????

When you get it running how does it sound?? Any poping ?Or is it running rough?

No it seems to rev up fine

Did you check the vacuum lines? Any loose wires?

I did...... but I really dont know much, everything seemed fine.

Ok im stumped.Mabey somone else can help.

I just had a mech. clean the throttle body, could that be involved, what could be some problems, please help!!!!!!!!!!

Hey, I had the same problem a couple month ago on my 99 Explorer.

I had the IAC (idle air control) valve motor replaced. It was about $120.00 with labor.

hope this helps

Another friend said the same thing, is it true that you can take it off clean it and re-install it, and if so what would be the best cleaner, carb cleaner ?

Gumout I think is the best.

Thanks!

do i need a ohv IAC ?

Replace the IAC valve and your problems will be solved. A new Ford replacement part will be around $80.00

definitely replace the IAC valve....and definitely do it yourself. I was having the same trouble just 2 weeks ago and that turned out to be the problem on my '95....cost me about 40-50 I think for the new valve, and was a CINCH to replace...took literally like 3 minutes...2 screws/bolts and it's off and back on.

if it can be cleaned , why replace it ??? I do my throttle plates an IAC once a year, along with a can of seafoam

actually you may be correct, however mine was definitely bad....sea foam, injector cleaner, all that stuff didn't help. I used a multi-meter to test the voltage, resistance, etc. and they were no good, that is how I knew the valve was bad and that I actually needed to replace it. Does this make sense Ramrod48? Or did I piss away $50.00?

nope sounds like you got it,,
