thanks for the infor guys. let me know how you make out badger..
Chevy, what would i do if i have the code read by a computer. i made sure the sensor was on tight and my buddy did disconnet the negative. its a slight possibility that the lack of hooking up the hose from the snorkel to the fuel regulator may have thrown the sensor off. the instructions to the kit shows a 4mm hose is supposed to be connected to the vacum fitting then onto the fuel pressure regulator. Apparently our Hummers don't have a fuel pressure regulater.. so K&N is sending a plug for the opening. I did cap the vacum fitting, so i doubt this is the reason...we'll see </div></BLOCKQUOTE>

If the intake is drawing in unmetered air from either the crankcase breather or the fuel pressure port then the fuel system will adjust until it hits its limit - then throw a code. Is it possible that the MAF element was installed 180 degrees in reverse - I don't know if this is even physically possible?
