Headers problem

[goeb34]

I had long tube headers put on a few months ago 2014 6.2 gmc, and every so often the engine light comes on so think its the O2 sensors cause i have no cats. Anybody else experience this? If so how did you fix it?

Did you have the truck tuned after the install?

What's the trouble code? I hope it was tuned after deleting cats lol

[goeb34]

It was tuned before and after and when i got the exhaust done my guy went thru and cleared the code again , its gonna be a week before he can get to it so im hoping its just the sensors

[goeb34]

Code will be checked tomorrow will post it when i know

Yes the tune can fix that but also remove code from report it at all. Then go in and disable cat warm up. Then just look over ve tables and reset all done.
