I have had a aem wideband in my vette for about 3000 miles. It started acting funny today.I drove for about 20 miles and I look at the meter and it is pegged lean 18+.So I hook up HPT and start scanning. My o2's are not doing this so I think it is my wideband. Would it be my sensor or controller? Seem to work good cold but the more you drive the worse it gets. Thanks!
PS: I was running in SDCL on this scan and tune!
