so after installing new test pipes and catback im gettin a p1273 code and a p0113 code keep in mind the car has been running same set up minus catback for quite awhile codes wouldnt bother me but seems to have lost power and supposed to be going to track in 2 days needto get this figured done all relearns i can think of with no results only monitor that hasnt ran yet is evap.. thanks in advance!!

 

Get a tune, your car is not running so great with the breather mods and not knowing how to handle it.

 

tuned car a year ago only thing thats changed is resonator and muffler since cant imagine that is enough of a difference to retune

 

Something went awry get to a tuner and check af ratios.

 

Ah, sorry did not know that.

For anyone who is more knowledgeable:

p1273 = Air Fuel Ratio Sensor 1 Lean Shift Monitoring Bank 1
p0113 = Intake Air Temperature Sensor Circuit High

Did some quick searching, can you check the MAF, and that the intake is clean?

 

thats what i am afraid of especially being a nitrous car kinda takes the fun out of it lol i did try cleaning intake will clean maf right now
