I have a very lean cruise problem, AEM wideband goes blank, logger shows AFR of 18 to 20, o2 volts go to .00 to .02 . The EGT has to be above 1100 for it to start leaning out .
The rpm's have to be above 2200. Vacum will not fall off or rise. Low, Med and High trims have not changed from 118. If I let up on the gas slighty for just a second then go back to cruise all is good for 2 or 3 minutes then it will do it again. I have replaced the o2 with a known good one, the 2G MAF is in good working order according to the logger and the shop maunal, TPS is good, had one boost leak and fixed that, fuel pressure is okay at the time of the malfunction. This all started after a 12:90 pass at the strip last friday
when the Alt started charging at 16.8 volts. Also I have by passed the emanage with no
change.
90 AWD TSI 16G, emanage blue with the normal bolt on's.
Yes I know that the answer is out there but none of the searches that I have done relates so can someone please help with maybe a link to a
similar problem.
