I need to get my car registered and i need get etest done asap. if anyone can help me out with what to do or what can be done it would be greatly appriciated.

thanks,

well you need an ACV (or just a hose) and an air pump to pass the e-test because you need to inject large amounts of air into the exhaust port ...

What else you got besides the cat ?

hugues-

 

ur #s are alot better then mine...but still...****...lol...

we both need a "fake' one done......ASAP...i think i speak for alot of Rotary owners=)....

anyone can help.....with 2hours of the GTA...i l GO!

 

i do got that air pipe connected to the cat and i changed oil before i went to and used highest grade gas and that garantee emission pass bottle. and wasn't even close to passing. any other suggestion?

 

sparks?...

TPS proberly adjusted?

 

oops!!

 

Higher Octane is harder to burn... Why would you use high grade gas running an NA?
That could have helped ur emissions some right there..

 

i think u should mail the company who made that emisisons fluid crap.....send them a copy of the results and get ur money back.....

sorry...cant help u since i dont plan on passing my etest anyway.......im just gonna cheat and get it over with

 

The numbers look like you're running no cat at all!

Is the car perfectly tuned?

Check ignition timing
New spark plugs
New spark plug wires
Verify all spark plugs are firing
Check TPS
Verify ACV is working properly
Air pump not slipping?

What type of cat? just got a generic one and flanges welded in? it might already be toast, rotary's exhaust heat make piston motor's heat look like hairdryers.

Does the cat have anything inside it?

 

Sounds like something is very very wrong - I'd verify timing first. I've passed NY state emissions (on the dyno) with no air-pump and one highflow cat. All I did as prep was a simple tune-up (spark plugs, oil change, clean air-filter, fuel-filter, verify timing/TPS).

 

cat wasn't a direct bolt on a buddy had to fabricate it. but numbers seem too high with a new cat. i wasn't even close to passing cause my friend cuzin was going to pass me if i passes half of the things or was close to passing but he couldn't do nothing cause it was not close from passing. and as for higher octane i dont think it would make a huge difference if it was lowest octane gas. it seems it could be the cat or something big in the engine. i'm going to have it checked by my uncle and check all the stuff suggested.

 

Thats like running no cat at all...

Make sure your airpump is working.
Air filter cleaned.
ACV is working.
Run fuel injector cleaner to make sure injectors are not stuck open.
O2 sensor is good.
TPS set properly.
Pressure sensor is connected. (if bad connection or unpluged, it will run full rich)
Use 87 octane.
Make sure cat is RED HOT before doing the test.
Check compression on engine.

 

Make sure the car is HOT before the test is done...no way it's gonna pass on a cold start. Best off to drive it for 15 minutes or so before the test...

 

yea i heated my cat before the test and you see no smoke comming out of my tail pipe and forgot to add i have an aftermarket muffler from ractive and i think 2.5'' piping cat down. i check the air filter, oil changed, check my plugs and wires most of the stuff listed on top before i went to do my test

 

That's your problem. Try this: http://www.autopartsauthority.com/ca...990~parts.html

 

you cannot run a non-rotary specific cat on a rotary. it will burn up and be no good in literally minutes.

pat

 

I need to have mine retested; I was told change oil & plugs, run car real hot before test then add 2 litres of methyl hydrate to tank that is near empty and bring to etest station- hope for pass!

 

wtf is wrong with you people digging up all the threads from 2005?

 

hahaha
