So i failed bad my HC% is measured at 1248 and it has to be 121 to pass and is considered a gross polluter at 296,Also my CO% was 4.98 when i need a 0.76 to pass and its considered a gross polluter at 2.26 idea's guy's?

 

with all those mods, no wonder it failed, are you using the stock cats?? is the air pump still attached??? with all the porting of the intake and ect its prolly throwing off the emissions,aux ports removed also too i bet...

 

I still have my cats intact with the main cat being only a year old. The smog pump is hooked up. Basically all my emission's has not been touched. Im just wondering what i should look for next?

 

Also does the octain number of gas that i put in have an effect on the result's?

 

way rich, it almost indicates a faulty cat or bad plugs. do a full tune up, adjust the TPS to spec and lean out the variable resistor to where it runs ok but has a lightly lumpy idle.

 

There is a table in the FAQ for FC that tells you what to look at if you are not meeting emissions.

It breaks it down quite well

 

Ok i was looking through the archive.....Also i lost the check valve for the intake manifold the one that goes behind the acv. could this be a problem? Anyone have one ill buy it?

 

I went from 6004 hc's to 64 with a 121 dollar maremount main cat, and a ls1 airpump running 100% air into the cat. woooo for jerry rigging

 

hook your airpump straight to the main cat

 

Read the fsm, Fuel section, and make sure all the components of the ACV are truly working along with the timing, new sparkplugs, air filter. Even change the oil prior to the check (part superstition).

Also rid yourself of that intake resistor *mod*. And get a checkvalve.

 

Ok i removed the resistor it wasnt on when i did the test. And for some reason that screw karack was talking about was set to maximum rich...? Also i have new 10mm magnacore wires and good plugs.

Will having the screw set to full rich cause me to fail?
will having no intake check valve cause me to fail?




Thanks guy's.

 

Add alcohol to the gas, add a gallon for like 4 or 5 gallons of low octane gas, drive very conservatively, it works.

 

I don't see the checkvalve making you fail. I THINK it was made so the exaust gases from the EXAUST PORTS can't backtravel from the exaust into the ACV and airpump area and possibly back thru the Split Air Pipe. It's best to have one.

With a HOT engine at idle, one at a time, pull one of the two vacuum lines off that sit just above the ACV and feel the rubber hose to see if they are pulling vacuum. The VAC hose NOT the metal nipples. Both should be pulling a vacuum at idle with a HOT engine.

 

Good input thanks^...


Now one more question what about the screw being turned to full rich if i turned it to full lean how would that effect my hc% and co%?

What kind of alcahol? it doesnt say in the faq. Anymore suggestion on how to use it?

Thanks guy this has helped more than you know!

 

It's best to set it to the leanest amount before it starts stuttering and what not. Less fuel = less hydrocarbons. I've always passed with it turned as lean as it can go and still run.

 

Your acv is not working. Get a new one.

 

If you want to pass, change your oil and oil filter, spark plugs, and o2 sensor. Run your car down to about quarter of a tank, making sure the cats are nice and hot, and then pour in 2 gallons of denatured alchol(found in the paint section at home depot for around 20$) and cruise over to the smog station not exceeding 3 k rpms. I passed doing this WAY under the limit with almost no emissions at all, the guy check my engine bay 3 times with a flashlight and had no clue. ;D

 

Oh yeah i almost forgot, when your done passing the **** out of your smog test make sure you go to the nearest gas station and do a fill up with 91. youll be alright.

 

Can you elaborate on that statement more?

 

"hook your airpump straight to the main cat"

would that hurt the cat at all? and is that effective not connecting the ACV?

and the alcohol thing, would that be a ok thing to do for a turbo?

I have the ACV blocked off right now, because there was a screw that was mis-threaded by the last person who owned the FC, i used gasket maker and blockoff plate for the ACV.
But i do not know if that will pass test-only smog and if it will be ok connecting the airpump to the cat directly

Btw, I am using a Bonez Hi-flow, hopeing that would be better
