so after a long tube install ( done several months ago) if i change the front o2 sensors ( used denso) but reuse the stock rear ones for the rear o2 sensors ( which i did ) will this cause the motor to constantly try and compensate for what it thinks is a deffective cat by adjusting A/F? im having a bad idle problem that is getting worse and was fixed my replacing my front o2 sensors ( used the stock ones right after the install) but now im having the same problem. i have another thread titled "idle issues getting worse" for more info if needed.

trying to see if a tune would correct my idle problem by deleteing the rear o2 and compensating for the lt and bbk intake install. as well as the AIR delete

The PCM does not compensate for a bad cat.

You need some tuning for the LT's and BBK intake.

You need to tune after a header install?
