Re: faild emissions today
HC is unburned fuel.
I think that your catalytic converter is shot.
You say the check engine light was on?
Did you get the codes read?
How many miles on it?
It could also be the O2 sensors have failed or they are not reading properly.
Sent you a PM.

Re: faild emissions today
catty converter passed emmisions.... um 165000 miles... i just replaced the 02 the codes i got were left bank 02 evap leak cylinder 6 misfire and egr running at 10%... i replaced 02 cleaned egr tightened gas cap an replaced plugs coils and wires.. now its just a misfire cylinder 6 when i get the car read....
this just started-----> when i rev it in park it starts to cut out at 4000 rpm... it takes a second when i first star it...
i was thinking injectors or and fuel filter
