5.4 pinging
my 99 e150 with 5.4 and 45000 mi just started pinging an rattling when i put a load on it. i don't know if it is because i added a k:n air filter or not. it started about a 2000 mi after i added it. i tryed injector cleaner didn;t help. i tryed a tank of 93 oct. gas helped a little but i didn;t need hi octane gas before. any help would be great

I'd really doubt it's the k+n. They don't do much of anything. The quality of the gas seems to be getting worse where i live (New Jersey) so I'm starting to gas up at name brand places. My 5.4 van doesn't seem to suffer but my 4.6 t-bird is pinging alot. Maybe it's a knock sensor going bad. Good luck and report back what you find. -John

I had the same problem and just fixed my 5.4. It was pinging terribly under load and I was getting a code PO140 Insufficient EGR flow. I took the throttle body off and cleaned the ports (they weren't very dirty) but it didn't help. I tested the EGR valve with the vaccum trick and it was ok. I replaced the DPFE sensor (at autozone they didn't know what that was....it's also called a EGR valve sensor, I think). That did the trick. When I took the old sensor off, it had a lot of build-up where the two hoses connect to it so I might could have just cleaned the old one out, but since I had the part I replaced it. Runs great now.

real easy. two hoses that connect to the bottom of the sensor pull off, two bolts holding it to a bracket and one electrical connection. should only take you 10 minutes.
