I was driving and then my truck started to sputter so I pulled over and it died then I noticed the check engine light came on it would start back up thougb it wanted to, 45 minutes later I came back and it fired right up so I took it to auto zone and got a diagnosis to find the p0430 code which mention catalytic converter failure I was in a rush to get it fixed since I use it for work so I just took off all of the catalytic converters well that worked well for about a day then it again died but would start up shortly after if I let it sit, I am not to car savvy if someone can give some insight to this that would be great

 

Btw it's a 2006 Ford ranger 6 cylinder 3.0

 

Did you ever get it fixed for this? I’m getting the same code.

 

did you remove all of them? how many miles on the odometer

A Ford P0430 code means "Catalyst System Efficiency Below Threshold (Bank 2)," indicating the computer sees the catalytic converter on Bank 2 (passenger side on many Fords) isn't cleaning exhaust gases efficiently, often due to a failing converter, bad O2 sensors, exhaust leaks, or even engine misfires causing issues like rough idle, rotten egg smell, poor performance, and the check engine light. Diagnosis involves checking sensors, exhaust for leaks, and the converter itself, as common fixes range from sensor replacement to cleaning or replacing the catalytic converter
