Bank 2 Lean...


Recommended Posts

Vacuum leaks or broken or split vacuum hoses, loose or missing EGR valve, loose or missing oilfiller cap or dipstick, loose intake manifold gasket are all first candidates for one bank lean and the other not. Dirty injectors (a tank of 93 octane and a 100-mile trip on the freeway may cure this), and dirty air cleaner element are possibilities. Do you have any other codes?

The owners of 2000-2003 Caddies should keep a couple of crank sensors in glove box. :)


By the time I get my 2002 Eldorado, I expect they'll have been replaced.

There is no means of avoiding the final collapse of a boom brought about by credit expansion. The alternative is only whether the crisis should come sooner as the result of a voluntary abandonment of further credit expansion, or later as a final and total catastrophe of the currency system involved. - Ludwig von Mises
