I read the "archives" here about different CEL situations.....

I too have the notorious 0138 code
(o2 sensor circuit high voltage)

I read this thread: (https://dodgeforum.com/m_311114/mpag.../tm.htm#311531).

Based on what I have read here and my basic DIY knowledge I want to replace the catalytic converter and replace the after cat o2 sensor.

What do you recommend in terms of an aftermarket "plug-and-play" catalytic converter? An OE one is pricey!!

Thanks again,
Chris

get a car-sound cat... you can find them on e-bay pretty reasonable. i'd go to the car sound website http://www.car-sound.com/ and find the p/n, then go to e-bay and find it there...

Thanks again Steve - thanks for replying to my two posts!

glad to help!
