If you get pulled over for exp. plates it a $110 fine and a possible tow fee

 

you have a 1998 si and you failed? something's wrong with your car! borrow a cat from someone....replace yours

I juts got my e-test yesterday and passed with flying colours, and i have I/H/E , 2.5" cat-back...and my cat is the original one from my car! ...plus I have a 1993!
So i'm guessing you shouldn't have any troubles passing especially if your car is 5 year newer than mine, something must be really off ...

 

Hmm,

Lets get a few things cleared up here: How does the exhuast smell? (now I don't mean take a huge wacking huff man - a wee sniff should suffice) If no sulfurish smell, we can assume the cat is not rotted. How is the colour of the exhaust? is it somewhat visible and a black sooty deposit is at the tail pipe - you could be running rich. Running rich could be caused by 02 sensor not getting the correct readings - look for a possible leak in your exhaust. Also check your fuel filters - when was the last time they were replaced?

Once you do some checks, run a test to see what (if any)codes are being generated.

Then..


Give the car an oil change, clean out the air filter, run a bottle of "guaranteed to pass" and run the whole tank through. Fill up with clean gas, and drive the car "spiritedly" for 30 mins before going to the E test. Then keep the car idling while waiting for the test...

 

I passed.



I was looking for excuses to run up mileage to use my tank with 'GTP'... before my desk, I was revving the engine at red lights... even in the left lane behind people...

I got more than a few weird looks.. hahaha

thanks for all the comments.

 

unhook your battery for a few mins to reset your ecu. stock o2 only measure the eshaust form one cylinder anyway. check your timing too. you can always tweak that to pass but you will have no power
