New guy, I have a 2001 24 valve and a 97 12 valve that is my feed pickup, been lurking for some time would like to make some mods to my 12 valve soon, to make it a bad ass tow rig for pulling cattle, loads of hay campers etc. As of now the 01 is my driver and is pretty clean don't have a lot of plans to mod it too much, I'm experiencing some dead pedal and the engine is loping once the fuel level gets to or below a half tank, will hard start when it gets hot, have had the codes pulled. I'm getting p0234 and p0216 added a fass system to it the loping didn't really start until after I had installed the fass, any input would be greatly appreciated.
