Check engine codes PO133 PO153

[wvragtop]

Getting these codes. Car stumbles a little bit before it warms up. Feels like it surges even after it warms up a certain RPM on acceleration. Doesn't happen all the time. Imrc delete. Long tube headers no cats. Supposed to have tune from Bama remove rear cats codes and I am RC delete along with air pump 4 long tube headers. New O2 sensors installed. Not exactly sure where to go from here

Found this while searching those Codes...looks like it might help your issue:

gaaah...throwing P0153 code

I'd also recommend an actual Dyno Tune if you deleted the IMRCs.

Yes this guy on that post same problem. Sounds like moving the O2 sensors to a primary to maybe the ticket
