Ok I have been gettting this code on my car for the few weeks.P1406 - DPF EGR Sensor Downstream Hose Off or Plugged While driving as well as P0420 - Catalyst System Efficiency Below Threshold (Bank 1). They both come on together every time. Now I changed the DPFE and both hoses and rest the light about a week ago and the check engine light keeps coming on and it is the same 2 codes. I'm really lost here and my car is running like a bag of crap so if anyone can help it would be great

Thanks Brad

Any chance your catalytic is clogged up real bad??

i don't think so cause i don't have a hard time starting it. I hope not its like $850 from the dealer and its like 2-3 months they told me

I had one clogged up real bad in a jeep, it started, but it ran like s*** until eventually it just wouldn't start anymore.
I'm not sure I can offer anything else though.

I believe Jegs has a high performance one from Magnaflow that remains in the stock location. I believe its $198.99 or something like that too.
