Yup failed again on the first try, I knew it was going to be bad, I smell gas when idling.

State Standards Mine

Hydrocarbons 220 Failed 452
Carbons Monoxide 1.20 Passed 0.72

No other things were checked, they asked me to idle and then i had to hold 2,500 rpm's for awhile

I knew it wasnt good after seeing Second Chance Test for both test and the time running out after like 2 minutes.

O well I better get into that chip tuning very soon.


I have untill Feb 22nd

yeah i think i need an o2 sensor for starters and a nice emissions chip and disable my drivers fan to heat up well over 220

Mad-Mic

passed before didn't it? fix the O2, get'er hot and dump 2 bottles of 90% isopropyl alcohol in it and run it up there on less than a 1/4 tank. i chanced my 02 sensor out and bingo worked for me

yeah i failed last time on the roller i went back again and they didnt do roller but idle. this time i went right to idle test as well as a 2500 rpms test in park. failed by double on the hydro's passed everything else.

yeah definitely starting with a new air filter and o2 sensor, and need to tune down the timing alittle also i think i am at 8 or 9.

this is going to be fun every 2 years!

Mad-Mic

when i passed i was at 12 degrees advanced

emissions was a sore subject for me till i passed thanx to the lovely lady workin that morning. i have no cat a 2inch rust hole in y-pipe and numerous rust holes at every weld on the flowmaster cat back, get someone to give you a receipt for 400 dollars of work theyll give ya a waiver.

MdFormula350

ehh i might make that the last resort, but i would rather pass on my own.

i am data logging my car now and want to see whats going on, it might be something easy.

Hey,

Did you ever get your car to pass? My RS keeps failing...

12/17/05... HC 278(220 limit), CO .60(1.20 limit)= Failed HC

Go home, hook up A.I.R. line to Catco cat...

12/19/05... HC 360, CO .42= Failed HC again!

Help!

Hell, I already have the timing set to 0!

Im wondering if my diverter valve is stuck. Imma do a full tune up and check the diverter valve and let you know what happens.

What's the latest, Jay?

JAYDUBB

Hey man...

I checked the Diverter Valve (per Haynes manual) and verified that it works.

Imma do a full tune up (cap, rotor, wires, plugs, AND ignition coil just in case...) and let you all know the results. I havent been able to do any of that yet. I was sick last week PLUS I had to get a new downpipe for the GTP. I hit something and broke the flex-joint. Thats why I was driving the Camaro daily in the first place. And to add insult to injury, I have to put another T-5 in the Camaro. Its humming its a$$ off! I think its about to take a dump...

But... enough with the whining. I will keep you all posted!

i see your running your cat still, are you still on stock manifolds and air pump? what is your water temp at when you go in? should be HOT. 220+ when they hit the rollers. full tune up would help also a O2 sensor. i'm sure your is shot and this really lowers the HC's. you already have your timing down. goto the drug store and get 2 bottles of 90% isopropyl alcohol and pour that in on a 1/4 tank of fuel next time you go.

i don't run a cat/airpump setup and at 12 degrees advanced i passed. 02 sensor did it for me.

JAYDUBB

Well GOSH Mic, you have a VETTE. They only passed it because its a VETTE!!!

I will try the alcohol after I tune the turd up. I will be wrenching on it this weekend...

Mad-Mic

if that was the case i would of passed LAST spring not THIS spring

JAYDUBB

The plugs for cylinders 4 and 6 looked like CRAP.

I will take it through on Tuesday. Wish me LUCK!!!

2new2funny

Good luck!

JAYDUBB

HC= 98 ppm (limit 220)
CO= .53 pct (limit 1.20)

Thank *** its over (well, at least for 2 years!!!)!!!

Oh... I think I was "fast-passed"...

MdFormula350

2new2funny

Great!
Now, in a couple of lines, what do you think did it? That's a big change in numbers!

JAYDUBB

Full tune up including the cap, rotor, plugs, plug wires, ignition coil AND the O2 sensor. My air filter, breather filter, and PCV valve were all new. And I recently changed the oil. Notice in a previous post that I said the the number 4 and 6 plugs looked like crap.

Oh... I also ran a half bottle of SEAFOAM through the throttle body, a half bottle in the oil, and a FULL bottle in the gas tank.

Mad-Mic

good stuff man glad you passed!
