I see from the emissions report you posted that your car has a single exhaust. I'm guessing this means you have an aftermarket setup of some kind, unless that was a mistake. What kind of catalytic converter(s) are you running? How old are they? Has any of the emissions system been removed? You passed the test at idle but failed when the car was operating at a higher RPM. I'd bet this means you have a bad cat. Depending on whether Washington uses under-car sniffer probes, it may also mean you have a small leak somewhere ahead of the converter.

Also, why does the emissions report say it is from June of 2006?

i think its the cat...
my car has a y pipe leading to two exhaust tips...
ugh... more money >_<

Its kinda hard since your test don't show NOx but lets assume NOx is high you are looking at replacing the Cat (it isn't that bad, what? 200 for the Bonez hi-flow?)

but see if you smell fuel from the exhaust, if you are running into a rich condition or if you didn't run in your Cat, you should fail HC at idle and pass HC at 2525

Well, it's just an opinion, but you passed at idle which indicates to me the catalytic converter is good.

Then they do some sort of on rollers driving test at 2555 rpm and you fail

That to me, means you might take a look and see if the car is going into CLOSED LOOP or not. The RX seven only uses the 02 sensor in CLOSED LOOP driving and at speeds over approx 1700rpm if memory serves.

So first you'd make sure your 02 sensor is inputting to the ECU on pin 2D or not. Like use your meter and backprobe 2D to see if you see 0.01 to 1vdc at idle or not. Or make sure the 02 sensors single wire is connected up or not. The connector is but a foot or less from the 02 sensor itself.

Can you confirm that Beverly put the car on rollers and was driving the car on the rollers at the 2555 whatever rpms?????? Mabe they don't do that where you are, what with that cheap **** fifteen buck emissions test. Come to TX where they do the real thing for about 35 bucks a pop.

CLOSED LOOP can be verified on a series four by .....puttting a single LED into the six socket green check connector near the battery...........disconnecting the TPS plug................and with a fully HOT engine, getting in the car and putting the shifter into any gear while holding the clutch pedal down (duh1). Then slowly reving the engine to over 1700 rpm and watching the LED you installed. The LED should start flashing on/off about 4hz as you increase the rpms over the 1700 figure.

If it starts flashing like that, then the 02 is being seen by the ECU and is going into close loop driving. Meaning all is well on that front and the problem lies elsewhere.

EDIT: You do what is described in the attached jpg, except you don't have to disconnect the neutral switch if you hold the shifter in some gear while reving the engine. You/we don't need that dumbass monitor in the jpg either. Just a single, cheap LED from Radio Shack.

judging from the high carbon monoxide and hydrocarbons you have unburnt fuel coming out the back, (running rich) likely is cat, or could always be a misfire. just do what i did, be good friends with an inspector, buy him a case of beer, input your car's info and run a diff car.

HAILERS

Yet for some unknown reason, he does NOT have high carbon/hydrocarbon at idle. There IS a reason.

TYko

the car not being in closed loop is def a possibility, any other symptoms while driving the car or it just wont pass emissons?

TYko

cheapest bet is probably bribery although you may take a hit to your morality checkbook

HAILERS

No, there won't be any symptoms driving the car, just a failed emissions test.

Did they put this car on rollers and drive it on the rollers for the 2555 rpms test?

TYko

why wouldnt there be any other symptoms if something is wrong, like say an exhaust leak before the o2 sensor which would get louder when you get on the throttle?
