Eseries engine stalls at idle

Having trouble with my 2005 Ford Eseries, gasoline engine, about 162345 km on it. Check engine light came on, and the engine stalls at idle sometimes. I've also noticed a reduction in engine power. I suspect a defective fuel pressure regulator, especially since the error entry occurred right after I changed the fuel filter. Has anyone experienced something similar?

I had a similar issue with my Eseries. What kind of pressure drop are you seeing? And are you getting any specific misfire codes? Could be a faulty regulator, or even something further down the fuel system line.

I haven't measured the pressure drop precisely, but it's noticeable when the engine is under load. I don't have the specific misfire codes at hand right now, but the check engine light points towards fuel trim issues. Did you end up replacing the fuel regulator in your case?

Yeah, after checking everything, I had to replace the fuel regulator. It was causing all sorts of havoc with the fuel system. If you're seeing a pressure drop and fuel trim issues, that's probably it. I'd recommend taking it to a workshop to confirm, but that was my experience.

I took it to the workshop, and you were right – it was indeed the fuel pressure regulator. Repair cost was about 45€. Replaced it, and everything is running smoothly again.
