Can anyone point me in the right direction, I've replaced the EGR valve snaked out the pipes, new gas cap(OEM) and the MIL still comes on after a few weeks. I'm glad that I purchased a code reader tool, I use constantly on this car.

You need to get some time with a SDS to go into values to see what the problem really is ..No More guess work

locate a Indy with one ....


Many items to look at
hoses
connections
lines
switch over valve
valve

Did you
check for the proverbial brittle vacuum lines on the m104 to the egr valve?
