About two days ago my wife said the engine on our 2012 Wrangler Unlimited sounded louder than normal and the check engine light came on. We had the code read and found it's P0432 Bank 1. She drove it yesterday and for part of the day the check engine light was still on. She said yesterday the...

2010 rubicon with 70k miles. It’s run fine for 30k and no issues. Maintained it myself. Fairly stock. Intake on it and some LED lights. Nothing mechanical. For some reason now I’m feeling an issue with the trans/cat/exhaust. I’m not sure what is causing this issue. THE ISSUE: Driving...

I searched and read quite a few performance threads and it seems like the overall opinion is that chipping/programming, exhaust and intake are not worth the $ put in when it comes to power put out. My question is that - My JK has 144k miles on it and the other day I got a check engine light...

Just installed a "magnaflow direct-fit" catalytic converter & down-pipe into my '98 TJ 4.0L. (Magnaflow 23227 - MAGNAFLOW Performance Direct Fit Catalytic Converter for 97-99 Jeep® Wrangler TJ with 4.0L Engine - Quadratec) The holes in the down-pipe-to-header flange (between the oil pan & front...

I have had a total loss of power, RPM's wont go above 3K and Jeep wont go past 35 MPH. I replaced the dual cats back to the "resonator" or whatever that thing is. When I removed the old cats, one of them was completely empty and the other had the honeycomb material visible. Could the material...
