2007 Ford Fusion SE Stalling

[iLikePie728]

Hello,

 

I recently bought a used 2007 Ford Fusion SE with just over 107k miles on it. The engine was replaced a few years back. But for the past couple of months, it has been stalling or nearly stalling. The RPM will sink to below 500 then shoot back up 1000. Other times it will flat out stall. It mainly does this while the A/C is on. It will also shift at relatively high RPMs (~4000). Any ideas on what may be causing this are greatly appreciated.

 

Regards,

iLP

Coil pack???

Think Coil pack would set a check engine light-wondering if fuel filter may need to be changed? This won't be tied to the transmission but maybe the stalling. Better to start with the simple and less expensive items first:)

Check plugs and coil packs to start with, those are the simplest things it could be. If there's a check engine light check the code, any AutoZone or O'Reilly will check it for free.

What about fuel delivery system? Could be as simple as a fuel filter.
