I have a 1999 Expedition that has started intermitently dying after it starts. RPM's go up for the start, then it just flat dies. I can keep the motor running when applying pressure to the gas peddle, but as soon as you remove your foot, it dies. Please help.
Idle Air control Valve- period. 40 bucks- you're back in business. Top of intake manifold, center of the engine, almost touching the firewall in the back. Not the easiest to get to, but you can swing it. Two bolts and a gasket- that's it.
