Your header install
Not real sure yet I need to get that exhaust leak fixed.(cant stand to hear it )It sounds sluggish,but has alot more snap when you mash the gas.Ill get out the SC Data logger and do some testing with it .srry no pics I left my camera in my freinds car
C121A, C2114 and U0125 are probably caused from the battery disconnect. Step through the ESP/SAS reset procedure:
After prolonged battery disconnect the Steering Angle Sensor (SAS) needs to be calibrated. The SAS requires calibration anytime the battery or an ABS (ESP) component has been disconnected for any length of time. Steps to calibrate:
-Start the engine.
-Center the steering wheel.
-Turn the steering wheel all the way to the left until the internal stop in the steering gear is met, then turn the wheel all the way to the right until the opposite internal stop in the steering gear is met.
-Center the steering wheel.
-Stop the engine.
P2098 and P0420 are exhaust related. P2098 may be due to the leak. the P0420 is the common one seen with headers.
Code Details...
P2098 - Post Catalyst Fuel Trim System Low Limit. Set by a lean condition.
P0420 - Catalyst System Efficiency Below Threshold (Bank 1). Drivers side #2 O2 sensor
C121A- Steering Angle Sendor Not Initialized. Caused from battery disconnect, turn steering wheel lock to lock to initialize.
C2114- Dynamics Sensor Supply Voltage Low. ESP cut-off switch.
U0125 - Lost Communication w/Dynamis Sendor. ESP cut-off switch.

Ok thanks Mango,but where do I find the procedure for the ESP recal.? Do yo uthink if I put the high flows on the P2098 will go away? I still have a leak. I can hear it when the car is under a load,bt not idleing,or revving any Ideas?
Sorry my bad, didn't mean to imply there's a ESP recal. The ESP evidently takes SAS informationinto consideration when it's doing it's thing. Just step through the SAS reset.
P2098 is probably due to the exhaust leak.

Ok well .I think Ill have it fixed so I have no leaks this week.I need to cut a slit in the pipe so when I tighten it up it doesnt shroom/buckle.That tuner is great for those codes,not sure if anyone else has used it but it will tell you what it is and clear them as well.Mamma says car is alot louder on the outside than what it was,n sounds lots meaner. lol



but you made it. What a deal! Now let us know what you think of the performance.
