[QUOTE="Speartip, post: 461238, member: 23341"] Much has been written about this code . Figured share my experience . JSCAN came up P0430 code . Intially I was confused as to how to fig out if catalytic converter or other issue . Doing some research I learned faulty ignition or fuel system delivery can cause a P0430 code. Tripped over a UTube video showing how to actually diagnose a faulty C Converter. Using a infrared thermometer once engine heated up. Idle at 2K and check temp of CC on the intake and outlet side of the converter. The outet should be about 100 degrees hotter than intake . I'm at about 50 degrees so the thing is probably plugged up. I've got super smooth idle . But at 50 , 60 & 80 kph is runs really rough and hesitates. That is also a symptom of faulty CC. Lack of oxygen. On JSCAN you can read the live voltage values . Monitored mine and they are off to what I see recommended . Can't remember exactiy what they were saying . It's been a couple weeks since testing . Anyway ordered a non factory CC system of Amazon . Received that . Just found out today can get 4 new NTK sensors locally for roughly same pice online . These are the NTK part #'s for a 2008 3.8 litre 23159 down stream left & right 23566 upstream left 25186 upstream Right Do not attempt to use Bosch or any other brand of 02 sensors. Research online showed codes popping up using other brands. It has to do with incorrect voltage when other brands are used . The weather here is getting wet so found a shop that will install. Will update once everything Installed . [/QUOTE]
