so im replacing some of the sensors on my car,
earlier in the week i found out it had the origional knock sensor still there, from the 5.0 engine, i am now thinking about a new egr Valve, but dont know if i need to.
bottom line question: is there a difference between the egr valves located on 5.0 tpi's and 5.7 tpi's?

 

I don't know about the EGR but I do know there is a difference in the ESC for a 5.0 and 5.7. Easiest thing to do is look up and compare the part numbers online like at autozone.com or another parts store.

 

i just researched it and the esc info on speed density vehicles is in the PROM programming: DONE
thanks btw
