To lower Nox you should have fresh oil and to decarbonize your engine you can use fuel cleaner by putting trough the trottle body while engine running. You can use half a bottle and little by little. Unless you have a vacuum leak, this will make a rough idle at low Rpms. Check all your hoses for vacuum leaks. Also its a good idea to use a bottle of fuel cleaner that you can put with a full tank. You can get it at Autozone or Kragen. Don't get the cheaper kind 'cause it might not work as good. If you didn't get new spark plug wires its better to check your wires with an ohm meter 'cause if they're not within specified range for your car, the car might run good but it makes big difference on Nox readings. If you drive your car almost every day, it's advisable to change your wires every two years.
O2 sensors are supposed to be changed at 40k to 50k of life. I had a sensor was reading okay and the car wouldn't pass smoke check until I changed the sensor.
Catalitic converters are supposed to last a long time. Although if your O2 sensor was bad it will shorten its life. They also have a life warranty of about 50k miles. Unless it was the original which should last longer.

I too have a high pitched annoying whistle at freeway speeds. It sounds like it comes from the dashboard or speedmeter. its a 2005 corolla S. It is aweful. I don't think my dealer has done much to try to fix it. The only way I can get it to stop is to slow why way down. Has anyone called toyota or found a cause?

I have a 98 Corolla, and the Gas pedal is starting to stick, has anyone experienced this problem and if so, what was done to fix it?

Have you ever had the throttle body cleaned?

This question will probably be my answer but where exactly is that? No, I have never had it cleaned.

This is serviced as a unit except the mast that threads into the base. Go see a local body shop for an estimate. The last I knew the antenna is an assembly from the base in the roof to the radio & has an amplifier in it. Lotsa bucks. Good luck.

We have seen stuck piston rings on these engines that leads to a quart every 500 miles of use. You need a "ring job". The timing chain is a "fix it when it's noisey" thing and not a scheduled maint. item. The ring job with timing chain runs about $2000 with shop rates of $60/hr.

I have seen most of these noises coming from front doors that don't fit tight enough. When you hear the noise push out alittle at the top of the front doors--this should change the noise confirming the diagnosis AND which door is out of adjustment.
The only other thing I have seen, and it is rare, is windsheild mouldings that buzz at higher speeds. This noise is very hard to duplicate so it may be just easier to do the repair which is to have a body shop reseal the mldgs to the glass.

The Tacoma overfender gaskets falling off was a problem unique to certain Tacomas & addressed in a TSB.
You Corolla should be fine.

Is the noise on the passenger side of the engine compartment? Sounds like a timing belt loose from wear or stretching.
