I finished the 3.4 install in my Runner. On its first real highway test it went into what appears to be safe mode.

The cel is on

Pulled trouble codes

P0100
P0101
P0102
P0110
P0141

The first four codes look to be pointing to a failed MAF. The reason I believe this is because for P0101 the MAF is the only trouble spot listed. The MAF is also listed as a possible trouble spot on the other codes. This MAF is a salvage yard part. Any ideas?

The P0141 is the NO. 2 heated O2 sensor. I extended the wires to this plug by soldering in wire. Does anyone know if changing the length of these wires will mess up the reading.
