Hydrocarbons (HC) :

My Results : 7.0578 GPM FAIL!!!!
Carbon Monoxide (CO) :
State Standards : 30.0000 GPM
My Results (Which I'm kinda proud of  ) 286.1601 GPM FAIL!!!
Oxides of Nitrogen (NOx)
State Standards : 2.5000 GPM
My Results : 0.3114 GPM PASS!!!
Ok so what can make me fail 2/3 and why would I pass the third?
I'm pretty sure I had a gas leak from the fuel pump to the carb when I got tested the first time which is now fixed. A little info for ya. |
this appears to be an overly rich running engine....co is way too high...
I bet your plugs are black in color not a light brown..too much gas not enough oxygen....could be EGR ...
