I just failed due to high HC.
My DP to cat connection was loose so I had a major leak there during the test. Found this out when I pulled the cat to make sure the element inside wasn't cracked or damaged. Once I loosened the four bolts at rear of the cat, I could just pull the cat off the DP. I also need to fix the end of my dp it is definatly out of round. Would a big leak there cause High HC?
I am going to fix that before the retest.
I also replaced plug and wires, but the old plugs all looked good and showed no sign of a missfire. I put the factory intake on.
my HC were
15mph 96 max is 77
25mph 99 max is 59
everything else was well below limits.
CO
15mph .07 max is .50
25mph .06 max is .41
NO
15mph 187 max is 541
25 mph 147 max is 498
%CO
15mph 14.6
25mph 14.7
%O2
15mph .4
25mph .4
Any thoughts or suggestions?
TIA
