Okay guys;
Got up this morning and felt the snow and ice had subsided enough to drive my 06' Viper Coupe the four miles to the Emissions Testing Station here in Colorado as my plates are due here in January. Never had a care in the world as the last time I tested the car in January of 2010, it passed with flying colors. As you are aware, the only different in drivetrain on my car is Full Bellanger exhaust (Headers, Hi-Flo Cats and Cat-back, Fidanza Lightweight Flywheel and 3.55 rear gears), all of which were present on my 2010 Emissions test. I have done absolutely nothing with the car since then. It is exactly the same. Anyway in January 2010 here is what I had:
HC Tested: 0.4506, Limit is 1.2000 (Pass)
CO Tested: 4.5271, Limit is 15.0000 (Pass)
CO2 Tested: 479.6283, No State Limit (Pass)
NOx Tested: 0.4057, Limit is 1.5000 (Pass)
Evap Test: Pass as Satte is just Pass of Fail (Pass)
Today, January 2012 I get the car warmed up real good then fill up the rest of thegas tank, which now all of a sudden my gas guage seems to just show 1/2 tank when full. NEVER noticed this before today. The results come back as:
HC Tested: 2.5819, Limit is 1.2000 (Fail)
CO Tested: 12.5480, Limit is 15.0000 (Pass but number is 3 times what it was 2 years ago)
CO2 Tested: 743.5807, No State Limit (Pass but number is over 70% higher than 2 years ago)
NOx Tested: 2.1485, Limit is 1.5000 (Fail)
Evap Test: Pass as Satte is just Pass of Fail (Pass)
I have no clue what is going on. Bad gas could contribute, but something else is going on. Check Engine light has never come on. It has always had the stock tune as nothing has ever been dumped into the computer. It had sat for almost 2 months up to today. Tank was only at 1/2 tank before I filled it up according to gauge.
I am baffled and not sure where to even begin. The higher readings would dictate:
High HC means I have too much unburned or partially burned fuel coming out. (I have noticed the mileage on my Viper was getting worse, but still getting around 14 mpg average.)
High NOx means high Combustion temperatures and or high Combustion pressures.
If I had high CO that means it is running too rich. But it is definitely running much richer than two years ago according to today's readings.
Anyone have an idea where to start or what to do? I mean the CO Viper Tech Glenn is no longer at Brandon Dodge on Broadway which means there is not a seriously good and trustworthy Viper tech at a Dodge dealership in the Colorado Front Range. I am somewhat very discouraged by this. I just am not sure where to start on this and my job and travel schedule is not leaving me with much if any time to deal with it at the moment.
Is it a problem with Cats, is it a problem with O2, is there some other problem there? I mean I have noticed that it seems almost like it has slight hesitation and some roughness when you first step on the gas after taking your foot off of it. It seems to run a little rougher between 1000 rpm up to about 3,000 rpm, then it smooths out. Then again I am anal on how it feels to me.
I don't want to seem like I am freaking out but I had never expected this type of a result to the test based upon the fact I have done nothing to the car since the last one and and only put 4,200 miles on the car between tests.
Help! Help! Help!
Thanks
Rick
