Fuel Problem

[explorer98]

People are going to get sick of me on here, but I forgot to say that when I did my 4.0 to 5.0 swap in my 98 explorer I left off the egr valve, egr valve position sensor and the egr vacuum solenoid. I know you can leave the egr valve off but do I need the other two hooked in order for the fpr to work right, or the fuel system in genral.

I don't know for sure, but 99% sure you will need all of those working properly for the computer to work properly
