I have a couple of engine codes that are coming up after installing my Kooks headers, cats and Corsa exhaust on my 08 SRT Jeep and I want to know if this is the norm for the nanny controls or if there is a special problem. Here are the following codes; P2097 Post catalyst fuel trim system too rich bank-1 P2098 Post catalyst fuel trim system too lean bank-2 PO153 O2 sensor circuit slow response bank 2 sensor-1 PO420 Catalyst system efficiency below threshold bank-1 Other than this I have a cold air intake by AFE and a diablo tuner that can't be used. So, let me know what you guys think, I am probably going to go with a PCM tune from B&G and back over the Diablo in my driveway....
I've got a similar exhaust but on my LX. I got P0220 and 230 I think...contact RDP Motorsport's dynosteve and he'll make you a happy camper all over again. He helped me and the codes are gone and allows for regular CEL's to come on if should something arise. Nice tunes fo sho!
