I've searched the old threads but it not clear what I should do with my 1987 944 NA. O2 sensor? Adjust FQS? CAT was replaced 2 years ago when previous owner also failed NO. Also I think the DME was changed to a AutoThority chip?
Any help would be appreciated
Here's the results:
At 15mph
Rpm=1795
%CO2= 14.8
%O2=0.3
HC=.22
CO%=.06
NO= 1073 Fai (max is 799)
At 25mph
RPM=1988
%CO=14.9
%o2= 0.2
HC=12
CO%=0.01
NO=1031 Fail (max is 738)
Thanks,
I love this car.
