Here's the gig...02 Xterra with 115000 miles.
Check engine had me replace knock sensors and O2 sensor about 400 miles ago. Had valve covers and a water leak fixed at this time. Since getting it, about 120 miles in P1163 code pops again. Put another O2 sensor in and about 300 miles, we got it again. They checked everything yesterday again and can't see anything, but it continues to trigger the code. There are no recalls on it. Shop suggests that Nissan flash the ECM, but there are no shops that will try it without an update. My fuel mileage has gone to like 12 mpg since this started. The only possible thing that the shop can come up with is hairline cracks in the exhaust manifold or an issue with the fuel control.
Any ideas from the site wrenches??? I'm not stoked about spending more jack since I dropped $1200 a few weeks ago.
Even less enthused about the local Nissan shop since they took 32 days to replace my steering box 4 years ago. (I know, what kind of sh*t is that???)
Thanks
