I have a 98 f 150 with the 5.4 and I'm getting an egr insufficient flow should I just remove and clean everything or just replace the valve

Your egr is probably fine check the metal hose that goes on the exhaust manifold and the two rubber hoses going into you dpfe also you vacuum selinoid for your egr looks like it has a cap on it

I have checked vacuum it's good I'm gonna pull it off and clean all the hoses and intake

Having the same proflem with my '01 4.6. I've replaced the EGR and cleaned the lines and still getting the same error code. I've purchased a new sensor but i haven't figured out where the sensor is to replace it.

Does yours run horrible between 1200 & 1800 mine is crap but I checked my egr valve and its all good but I'm gonna replace the dpfe if mine still is settin the code

It idles a little rough sometimes but that's about it.

I had that happen on a ford ranger I had and it ended up being the sensor that monitors the egr(cant remember what its called).

The sensor is forward of the valve. Its the black plastic thing the rubber hoses from the egr pipe connect to. Mine was throwing that code for a while and I replaced the valve and cleaned everything I could with no luck. Turned out my hoses were wore out and had holes.

Their are two dpfe and the vacuum selnoid it has a cap looking thing on it and that was the problem with mine also check the rubber hoses for holes

I'm beginning to think the parts guy gave me the wrong part. I was also thinking it was the thing with the medicine cap looking thing on top in front of the egr valve. The part they gave me looks nothing like that. Looks like i'm headed back to the parts store tomorrow.
