Hello everyone hope you had a great 4th. we climbed in the pace arrow and headed to Gulf Shores, Alabama. Had a great time with friends did not see much oil and that was good. On the way home got a service engine light read the odb and it said both banks running lean. 2001 pace arrow 6.8 the thing ran great. Any one have idea's.

I had my service engine light come on our 1998 coachman after pulling a steep grade and pushing it. Took it in for service, pulled codes and both banks running lean.

The tech claimed the computer sensor was prior to the current ethanol levels in gas, and since both banks were lean he said not to worry.

He disconnected the battery and cleared the codes. It happened one other time on a long hard pull in the Rockies.

You have several options to find what code set off the SEL. 1) The cheapest & possibly the easiest is to go to an auto parts store & ask them to plug into the diagnostic port and read the code. Auto Zone & advance will do this for free, others may also. 2)You can purchase a ODBII reader & check it yourself. 3) You can take it to a garage & have them read & diagnose the fault. The first 2 options will only tell you what the code is & what possible fixes are needed to remedy the fault. With the first 2 you can clear the code after reading it & see if it comes back before going to a service center. The SEL does not normally set a code if there is not a fault.

Hey thanks to PKendzor and disbike for the info I have a scan tool and all it told me was both banks running lean. I just finished checking vacuum hoses and the pcv hose and fitting looked good. I do belive I will take your advicwe and see if it comes on again. Sure glad I stumbled on the site. Lots of folkswilling to share info . THanks again

You're probably familar with this, but I saw it for the first time a week ago and had to think about it for a few seconds. The phrase was "And Robert is your mother's brother".
