alrighty. however, with the way our trucks are programmed, ur gonna need tat egr valve. even though u got tat valve blocked off, u still need to plug tat egr valve into the wire. she'll start burping and getting real grumpy if she dont have tat plugged in. tats why it's throwing up codes and causing ur car's computer to be confused.

if u live in california, it's against the law to not have ur egr valve. even if u got a full delete on, u still need to have tat plugged into the wire. any scanner when plugged into ur obd2 port will know tat u dont have ur egr valve and it will cause u to fail inspection. they're clamping down on tat nowadays.

if u need to get an egr valve for ur 05 model, and u dont wan to spend too much money, u can find one in a salvage yard. make sure the engine aint too messed up, and when u plug into the harness, u can test it by starting the engine. rev it a little and u can see it open and close.
