I have a 2005 4.0l base mustang. I see throttle bodies for 2005 to 2008 and for 2006 to 2010. What is the difference. There is a 3 year over lap. Will the one that says 2006 to 2010 work on my 2005.

may be it the problem of another throttle body.also check the ignition switch.

Check all of the battery terminals and cables and check the wires on the starter/selonoid, start from the battery and follow the cable out and check all conections , clean and tighten them and if it still does it the starter/selonoid is bad and needs replacement...

It sounds like you need an oxygen sensor. You are not getting the proper air-fuel ratio. murf427
