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 Used the search engine but couldn't really find the solution. Thanks
Headers? Predator? O2 sensor wires switched? Need more info, such as mods, when it started, did you do anything that popped them up?
Oh sorry, I have heads, cam, manifold, cai, borla, and Kooks with a Inertia tune. I did some research on all the forums and relized it was the headers but now what do I do?
Alright went under the truck to see if any wires were touching the headers everything looked good. Then, I decided to check if the 02 sensors where on and they were, so I turned them off and clear the codes. Now, I will drive it around a bit and see if they reappear.
I've seen 02 sensors re-installed incorrectly or dropped/banged aroud or left hanging during installed, its so much easier to zip lock bag them during the install and use a perm. marker to indicate on the bag which is which, if they cut any of the 02 sensor lines or got them hot with a torch there could be problems
153 and 420 can be turned off with the Diablo. Those are reading the rear of the converter. The 2098 bank 2 is the passenger side front and the 2097 bank 1 driver side driver side. You need to hook up the Diablo and at least look at the long and short fuel trims. Let me know if you see the numbers - or + greater than 10 consistently. I would also alert Stu. It is in the tune.
