Sounds good to me but why the "wait" in Line?? Here in McGoofy land [Ont] at least they have an appointment time at the garage, so you do all the above,bring it in at scheduled time & wait is only a matter of mins. engine is "HOT" from your run down the Hwy.!! Your still "gettin Screwed" but in a More" effeceint way!!!!!!!

You're high in CO so I think you need less hydrocarbon and more oxygen (you want that CO to become CO2) - which means you need to lean it out or increase air flow (new air cleaner could help). That'll likely raise combustion temp and yes, I'd expect that to raise NOx, but you said you're well under the allowable for NOx.

I would think that a slight advance on timing might help too, but I'm not sure on that one. If you have excess O2 in the exhaust, advancing timing might help?

The AirCare program is only in the lower mainland isn't it?

can you just take the air filter out for the test then put it back in after ??
I have been told to turn it off in the line up if it is long.

I'm glad we don't put up with this bollocks.

Seafoam additive can go in crankcase. tranny or in the tank - its up to you. Found at NAPA, Crappy Tire etc.

You can get Seafoam at Crappy Tire. I do 1/3 in the tank, 1/3 in the oil a week or so before an oil change and the rest goes into the intake.

Run engine to get it nice and warm before the procedure.
Disconnect the hose from the brake booster. It'll be sucking air and the engine will continue to run. SLOWLY pour it in while you give it gas to about 2000 rpms so it doesn't stall. As you get to the end of the bottle, dump the last shot in and the car will stall. Leave the car turned off for at least an hour. I've gone a whole day before. Now the fun part.... It'll take a little churning to turn over, but when she fires look out. Huge plumes of white smoke will beltch out of the tailpipes and cover the area like a spy car from a 60's movie. When that clears after about 5 minutes of idling, you take it for a rip of spirited driving. And when you punch it, you'll see puffs of white smoke in the rear view. That soon clears and as the theory goes, your engine's innards will be cleaner.

Now I'd be interested to hear from the real mechanics on this site. Is it a solution or just snake oil in a can? Please weigh in.

Years ago I watched my grandfather (licensed mechanic) fill a clean coke bottle with water, take the air cleaner off a early-60's Ford sedan (cannot remember what model, it was a V-8 and 40 years ago). On a warmed up engine, he held the throttle open (probably about 3500 to 4000 RPM) and he poured the water into the carb. He didn't 'dump' it in, but it was a fairly steady pour. I think was watching make sure the water entered as small droplets and wasn't running through as a liquid stream, and the engine did not stumble. HUGE cloud of white smoke and then a big cloud of black smoke after he had quit pouring water. He kept the RPM's up for maybe 30 to 45 seconds after he finished pouring. No more pinging.

I wasn't very old but I remember being shocked when he started pouring. Always thought that was one if the gutsiest things I ever saw a mechanic do.

...heard of that too. Was actually thinking of trying it. Water poured in in the right amount can really clean out the cylinder 'cause after all, it's making steam right? I'll talk to my mech. before I do it though..

Cheers on the info everyone..

 We used to do the water thing just after un corking the headers , to clean off the carbon off the valves to stop the popping, then reset the timing..

If you have alot of blow by you will probably be getting alot of "fuel" from your pcv system. I would recomend changing the oil. Your car is running rich at idle. I have had great success with running a combustion chamber cleaner to bring down #s but your carb would need to be adjusted once you have made any changes oil, plugs, cc clean etc.... 

Do you have to do this to get plates, or change ownership?    if not  maybe skip the test?     We only do it here in Ont when selling the car
