Hey guys,
A buddy of mine installed pypes longtubes on his car. He was issues free until he went to go lengthen the front o2 sensors( ran/drove fine without front o2s even plugged in). He lengthened the front o2s then took it for a drive and pulled codes P0135 & P0136. He then looked at the wires rewired it with smaller gauge wire and heat shrink butt connectors and now it pulls P2254 & P0713. What is his issue? Thanks everyone!
