system info

Ok, we went to Auto Zone today. The check engine light is on and they hooked it up. No codes came up only System 1 too lean, System 2 too rich. We are trying Octane Booster and a higher Octane gas to see if that helps. Any other ideas?? the engine light is still on.

RE: system info

One of yor O2 sensors could be going bad, but not bad enough to cause an O2 error. Just a thought anyways.

RE: system info

I am having somwhat the same issue with my 98, just replaced 2 of the O2 sensors because of the code for the sensors. Now the light is on again and the code is for to lean. AutoZone recomended using Lucas injector cleaner to see if that helps
