After putting in the eliminator value the check engine light came on. Then hooked up the electric modulor per instructions, the check engine light is still on, what do I need to do now to correct this problem. This is a 2004 Ford F250 4x4 60

 

you mean you got ridd of the egr valve??

 

If you delete the egr valve you will get a get engine light sometimes. If you have an SCT programmer or some other chips they will allow you to reset the code.

 

yeah but with no intake air temp diff how do u make the light stay off
