Excursion Scorched Intake Manifold

I'm having trouble with my 2006 Ford Excursion diesel. Only 54588 km. I think the intake manifold is defective. It's jerking on acceleration, has an error code, and the check engine light is on. Also reduced power, stalls at idle, rough running, and a strong, acrid exhaust smell. Could this be a scorched intake manifold?

The 2006 Ford Excursion diesel is experiencing issues such as jerking on acceleration, error codes, a check engine light, reduced power, stalling at idle, rough running, and a strong acrid exhaust smell. These symptoms suggest a potential problem with the intake manifold, possibly due to scorching. The suggested solution is to check for manifold pressure and potential vacuum leaks around the intake manifold gasket. Ultimately, a professional diagnosis confirmed a defective intake manifold due to scorching, leading to necessary repairs.

Sounds rough, man. I had similar issues on my Excursion – same symptoms more or less. Check your manifold pressure; that was my first clue. Could be an air intake or gasket leak messing with your engine performance. Is the exhaust smell really strong?

Thanks! By manifold pressure, do you mean checking for vacuum leaks around the intake manifold gasket? And yes, the exhaust smell is unusually strong, almost acrid. Did you also experience the strong smell?

Yep, that acrid smell points to the same thing I had. I'd say it's almost certain that's your issue. Time to visit a shop; this sounds like a scorched intake manifold. Seriously, don't delay, it'll only get worse.

Thanks for the assistance. The diagnosis was a defective intake manifold due to scorching! The repair cost came to 1180€. I'm grateful for your insights; it gave me the confidence to handle this.
