I am new to the forum. I have an 05 4.7L Quad cab auto trans. I recently replaced my EGR valve and found I had new unexplained Idle issues. I followed the thread to remove and replace the throttle position sensor wire and that seemed to help. Also I got to wondering about my Factory plugs and the inconsistency in gaps. I just got back from a test drive after installing 3923's at .040. Great advice it runs like a different vehicle. Also factory gaps ranged from .046 to .058. Thank you to everyone in the forum and I look to upgrage some stock parts in the near future.

 

i am glad you tok the advice from all of us. looking up past posts will help everyone out in some way or another

 

Welcome to the forum! Glad you found it helpful

 

Could someone post a link to the "throttle position sensor wire" fix? I've tried searching that term and several variations and haven't found it yet.
Thanks!
