Well, basically I got defected a month ago for having the car too low, too loud, catch can venting to atmosphere and having too many 'air' mods, meaning that i had both a cooler and a pod.
I chucked stock springs in, stock exhaust, made the catch can not vent to the atmoshpere and disconnected the cooler. I got the defect removed by getting a RWC and handing it (nicely) to Vicroads, only to get a letter a week later stating that i had to go to the EPA to get my car tested due to getting a defect.
I went there today to get everything checked out... after an hour of them putting their heads under, around and inside my car and engine bay and probing my exhaust the conversation ended up being something like this:
"Your CO levels are too high and the exhaust is too loud." said the mean old EPA guy.
"Oh, how high and how loud?" i asked.
"Well, the limit is 90dB and your exhaust is 91dB." replied the bad man. "And the high CO level means you are running rich."
"Running rich in a Cordia? Not possible!" i exclaimed.
So just before he packed everything away i asked if he could retest the CO levels again... but before he did, i grabbed my trusty green screwdriver and adjusted the rich/lean screw to 'lean'.
WOW! the CO levels went from 10% (rediculously high) to 1% (rediculously normal). The mean old epa guy was pretty cool in the end because he let me use his expensive equipment to check and adjust the richness levels, while keeping it all within the legal CO limits.
All i have to do now is come back with an even more stock (?!?!?) exhaust and then i'm all clear to face another day.
The point of the story is: don't get slapped by raw bacon because it will leave a stain on your windscreen.
