Hey guys I got a 2001 7.3 that had bad glow plugs. This past weekend I replaced glow plugs, valve cover gaskets, UVCH, ICP sensor, glow plg relay, and the pig tails for the valve cover gaskets on the outside of the valve covers. Now the truck has a miss and SES light comes on at start up and stays on. I pulled the valve covers back off and double checked everything. Can not figure out what is wrong or how to fix the P0075 code. From what I have read the P0075 is Intake Valve Control Circuit (Bank 1). Any help would be greatly appreciated. Now there is snow in the forecast for the next couple of days and this is my plow truck.
