Well in a limited sense some unburnt HC could be reburnt with the EGR installed, but in general it is used to lower the combustion temperature by flowing in noncombustable gasses. Lower combustion temps lower NOx emissions.

Unburn HC would mainly be removed in the catalytic converter. If the cat wasn’t getting up to temp or plugged the HC could be getting through.

I’ve seen on many cars that will stall and start shortly after because the oil pressure drops too low mostly from being around 2qts low.

My 99′ dodge pickup used to do this.

So check your oil as well.

That answer is a secret to everyone but Eric and the IRS. C:P

When you turn the A/C on it lets the computer know to bump the idle up slightly so you don’t stall the engine at idle.

Some of those products to guarantee a pass take 2 tanks to clear out. Also your HC could be high if you are burning oil I think.

Also if the timing is off, you could potentially be pushing un burnt fuel out the tail pipe. I would check valve timing as well as ignition timing.

These cars had timing belts so that could be the issue especially if the engine source was more interested in selling the engine than if it worked right.

Also a less than honest tip:

My dad had an 1981 280ZX that would not pass emissions. It had a bit of a blue smoke problem. So he drained the engine and filled it with straight 50 weight oil and it passed. Then he refilled back with the original spec oil after.

Also how close are the engines? I mean I know the Prizm was a rebadged corolla, but the 97 was an OBDII car and the 94 was not.

Looks like somoene uncensored it.

The word sensors on this site really need to go.

You could always pick up a Vibratach from a mower shop.

A vibratach is a wire that is wound up and you let a little out by setting the dial. You know you’re at the right speed when the wire vibrates in a figure 8.

Perhaps you mean “Certification Sceau rouge.”

In order to pass ziss test you must answer all questions en Francais.

Now along with the more “exotic” fluids.

Are many of these dealer only fluid?

[pcmdjason]

If you do replace the O2 sensor I’d go with a Denso over a Bosch if you have a choice. Denso’s seem to be faster acting. Bosch sensors tend to move too slow for asian cars and some people get codes with new Bosch sensors.

As someone once told me, don’t mix rice with kraut.

EDIT: Seriously? The word k/r/a/u/t is censored?

[pcmdjason]

I’m guessing there’s some pictures supposed to be there?
