Question about EGR valve
I have a 92 F-150 with a 4.9 L I just rebuilt the engine and when I put it in my truck I made a block off plate for the EGR valve it goes between the valve and the intake. My question is will it cause any harm to the engine, I read in an old thread that it could cause it to run lean, but my truck is running fine. Oh, and does anyone have the link to the site to show how to pull codes from the ECM.
