only other thing i can think of is a complete required overhaul of the emissions systems every 5 years with a emissions control tax. added on t make dalton and his fiberals some more money.
I have Vitiligo, it is there, but it is white (it = my eyebrow)

Just incase anyone was curious.

This was done after a tune up from Midas back in 2003.

Code: Select all

June 17th, 2003 -Failed

		Driving test	Idle Test
		Limit	Result	Limit	Result
HC ppm		71	53	200	41	
CO%		0.40	0.76	100	0.05
NO ppm		537	192	N/A	N/A	
RPM		2517	Valid	702 	Valid
Dilution	15.4	Valid	15.1	Valid
This was done after testing the car and spending $200 just on testing. They replaced the Catalytic converter.

Code: Select all

June 24th, 2003 -Passed

This was done after a tune up, oil change, brakes, new muffler and center piece from my mechanic. (Other things were done aswell)

Code: Select all

This was done after replacing the Catalytic converter again.

This was done after replacing the O2 sensor and putting in concentrated fuel injector cleaner on 1/2 tank of gas and driving to Waterloo and back and putting in a full tank of regular gas. (Next day)

This is what was done so far.

I have a 2002 Honda Civic. I know it's a lot newer than yours and is a smaller car with a different engine but my readings from last month are so dramatically different from yours. Did Honda do some major improvements in their engine/emissions during the 90s?

You are failing your CO% aswell?

No, I got a 0.01 reading when 0.37 was the driving limit and a 0.00 reading when 0.70 was the idle limit. I've tried to make the figures a little easier to read.

Hurk:
Your HC is way too high even after the O2 sensor. You have to fix HC first. CO will always be high if HC is high.

Misfire is the most common cause of high HC. Since driving HC is better than idel HC it is suspective that the distributor may be causing the trouble.

I assume in the tune up the spark plugs are all replaced. You should also inspect/clean or replace the distributor cap. Also check the condition of the high tension wires.

You should also do a scope test to make sure that all the cylinders are firing correctly. Also check timing to make sure they are not ********. All these causes misfiring --> high HC.

Most shops nowadays are reluctant to do proper diagnosis. They just kept changing parts cause they make more money this way. Too bad.

Thanks for your response. That's actually the most logical answer I've heard yet.. and you haven't even looked at my car.

Thank you. I'll let you know.

my 1993 ford escort with 550,000 km failed. had a cracked vacuum hose. cost of repair $1

mechanics estimate: new o2 sensor, new cat, etc

Failed a 4th time... I'm biting the bullet and going to a Etest specialist to test it out.

I don't get why anyone would fix their vehicle BEFORE doing the E-Test.. makes no sense.

I agree with warming up the car, but if you have to wait for the next e-test, then the car has cooled down.

For example, Can. Tire does not take appointments so if there are 3 other e-tests ahead of you, your car may be sitting and cooling down for 1hour plus.

I'd still do it, but just so that others know, this may be a waste of time.

Damn. Sorry to hear about all your problems. Taking my 2002 olds for a E-Test this week hope it passes.

Warming up the car makes a big difference. In London, Mufflerman at Wharncliffe and Baseline is great for this. The last two years, they took me in immediately after a 20 minute run on the highway in 3rd gear (Supposedly running the car in high revs helps burn out the carbon.). Here are my last 3 results.
July 2002

This was from the car sitting cold for 24 hours and driven 1 KM to the testing station.
LIMIT | READING | LIMIT | READING
HC 93 | 90 | 200 | 77
CO .52 | .09 | 1 | .04
NO 1046 | 46 |
May 2003

This was after a 20 minute run on the highway - testing occured immediately after driving in.
LIMIT | READING | LIMIT | READING
HC 82 | 17 | 200 | 17
CO .46 | .01 | 1 | .02
NO 948 | 493 |
June 2005

This was after a 20 minute run on the highway - testing occured immediately after driving in.
LIMIT | READING | LIMIT | READING
HC 72 | 35 | 200 | 31
CO .40 | .04 | 1 | .03
NO 948 | 493 |
A couple things to notice are that they are consistently lowering the limit while the car is getting older and that NOppm numbers will increase as HC numbers decrease. I've been told that this is because as HC's are processed, they release more NOppm. If the Cat isn't warm, supposedly more HC's will slip by which happened in my first test when I drove the car in cold.
