Hi I have a problem with my f-150..after sitting for 5 weeks I've had nothing but trouble with it the last couple of months...It surges while driving, won't idle, no power and stalls at the lights, I have already replaced the fuel filter and plugs but 2 "certified" mechanics later and they can't figure out what's wrong, any ideas or suggestions would be greatly appreciated, thanks!

 

Howdy and welcome.

Pull the trouble codes even if there ain't a check engine light. Here's how,

Thanks very much, turned out to be a map sensor..aparently it's a failing common to that model.
