I recently acquired a 2001 R/T with a 3.0 V6. Number 1 cylinder was having problems so I replaced the plugs, wires, cap and rotor. I now have a P0101 code which is related to the MAF. Between the MAF and throttle body there is a large pipe connection, probably for a vaccum line. I have not been able to find what is suppose to be connected here. This vehicle is driving me nuts, any help would be greatly appreciated.
