I have a 2007 F250 5.4 gas. I am having the problem of getting too much fuel to my injectors and has made my catalytic converter stop up. Has anyone run across this problem before? Any suggestions on what I should do? Thank you!

 

Check the fuel pressure, if it's too high, it'll run too rich. Other than that, maybe a leaky injector.

 

A sticky injector is not unusual but if one is over fueling you'll know it. The engine will run rough at idle and up to 1000-1200 RPM,the tail pipe will soot up badly.Easy enough to find which one is hanging. Lift a fuel rail and see which injector is dripping.

 

I clogged up a catalytic converter by having weak spark. Unburnt fuel made it to the converter. After a while, the converter burned out and clogged up.

It may not be caused by the injectors. Your issue may be spark related. Have you had the truck scanned for codes and pending codes?

 

Good point, redford...

 

early 2valve motor blowing plugs out of the head, 3 valve motors with bad COP, cracking spark plugs, and variable cam knock. Whats gonna be the bad part on the new 5.0 and 6.2 motors......

 

That was an expensive lesson for me.
