I picked up a 89 yj (carburated)6cyl 5 speed runs great and wheels even better, but at the test only emissions station it got flagged as a gross polluter here are the numbers
rpm 780
%co2 7.1
%o2 8.9
HC MAX 120
HC measured 2000
co% Max 1.00
co% measured 2.23
rpm 2431
%co2 10.5
%o2 4.8
HC MAX 180
HC measured 1367
co% Max 1.00
co% measured .28
It also failed on the EGR function test as well because it doesnt open up so Im replacing it, It had the OEM O2 sensor so I replaced that and Ive run a full seafoam treatment in her now. I leaned out the mix a hair(1/4 turn) on the carb per the testing mechanic's suggestion.
Anyone have any suggestions? Ive read tons on here about this abd I feel im on the right track ust wanna make sure im not forgetting something
