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
