well spring is coming and it is time to start thinking aout the fact I failed emissions just before I put the car away for the winter.
I dont know where to start and I dont just want to start replacing stuff because that gets expensive the numbers are kinda bad and any suggestions would be great.

the o2`s are original and the cat is 2 years old.

It's worth a try

 

what about tuning?

jim that has the black s-10 with the lt1 that goes to st.thomas alot with us in the summer had a tunning issue where he failed hc's in curb idle

 

I know you say your cat is 2 years old but to me it looks like you may need a new ones. Usually when you pass curb idle barely and fail HC/CO/NOx on 40km it's a good indication it's the CAT(s). I REALLY hate Ontario's drive clean program, they keep lowering the allowable amounts each year by 1.5% compounded! Oh and since that was 2003 the limits will now be lower then that.

 

I do this trick every year where I take my honda and put it on the sniffer and run it as my camaro.. Funny thing how CLEAN my ten sec camaro runs

But whats the deal dude.. Your car is a 96, the sniffer doesn't apply to you

 

In Ontario any car older than 3 years old goes on the "sniffer"
and our centers are directly connected to the MTO computers by VIN nuumbers so they cant run one car instead of another because they plug their computer directly into your cars computer to read the VIN.

I was thinking the cat could be shot also.I race the car every weekend from April to September so I would think that could be hard on the cat.

BTW I only have one cat as I converted to a single cat system.

 

I ran my cc305 for a few weeks without tuning and there is no way that it would ever pass emissions...anywhere. I think a tune and a good tune up just might do it. Is youre MIL on?

 

Ya I am running a 100 shot this year so I will need a tune anyway to be safe.

 

has anybody actually used this stuff?

I tried a search on google for it and most of what I found said diesel, is this just a marketing attempt to make people think "wow it works for deisel cars too!?!?"

 

That Guaranteed To Pass Stuff DOES NOTHING!! Don't waste your money on it.
I tried it in both my car and truck after failures with no results change.
You only get your money back if you can prove that all the original emissions equipment was working correctly with all the OE engine settings.

Try adding 6L of 99% isopropyl alcohol to 10L of 87 octane gas OR mix 15L 87 octane with 4L naptha (coleman campstove fuel). I have heard positive things about these concoctions, but don't have first hand results though.

 

buy an inspector.

 

I dont think I feel comforterable adding campstove fuel to my Z28(maybe a beater I would)

I tried the Guaranteed To Pass Stuff and it didnt work but I figured the 5 bucks was worth the shot.

 

Yeah thats what I was expecting
