Just installed my long tubes and i keep getting a p1133 code for the front 02 sensor not switching fast enough and now 0420 and 0430 for the from and back reading to close to each other. Truck idles rough and hesitates on takeoff.

Thanks

 

You need to get it re tuned

 

those are normal header codes and you need to get a tune to turn thr codes off.

 

Yup, retune needed

 

perfect thanks guys i was going to start replacing 02 sensors but i fired off an email to black bear for a quick tune and hopefully all will be well

 

i never had any codes for the front 02s with headers though... the rear ones just need to be turned off in the tune. and you can prolly swap the rear ones to the front if you have a problem
