I have a post going on in JBO about this problem... im hoping to have some better luck here...

just in case it gets figured out there...

but if you didnt read there i will explain here, nice and simple...

my a.f's are in the low 13.0s during idle and cruise... i am in the process of trying to figure out why... but when i turn on my AC the a.f's lean out to high 15's low 16's on average and sometimes off the scale on my aem uego wideband o2 sensor...

any ideas on how to control this?
