After about three hours on the trail today, CEL came on. Code was P0171, too lean on bank 1. I’ve searched it and am seeing everything from dirty MAF to cracked manifold to bad cats. I cleared the code, and did about another 90 minutes of trail then the ride home. No CEL and no codes and scangauge says system is ready.
Should I do anything now, or wait and see if the code comes back not on the trail?
I have noticed that my mileage has been getting worse lately.
Spark plugs, valve covers, and coils all replaced about 6-7k miles ago.
