For a pre OBD-II vehicle such as this one, the best thing to do is get it running as smoothly as possible, using normal maintenance and repair procedures. This means no misfiring, smooth idle, smooth acceleration, not overheating, etc. The same stuff you'd expect to work well in every day driving. There should also be no check engine light. This vehicle will ...

Open up the hood and look at the emissions control system label. That will indicate whether it meets California emissions standards or not. See this page from the California DMV for what to look for.
Also, at least for California (Not sure about other California-standards states), you can register a 49-state vehicle in California after you move there if ...

There are two ways to tell. Your local ford dealer can tell by decoding the VIN (the vehicle indentification number). It is usually located on the dashboard at the base of the windshield on the drivers side. If you look under the hood there is usually a sticker on the frame near the radiator that will say complies with California or 49 state emissions. The ...

Bank 1 is the same side as the number one spark plug
Bank 2 is the opposite side as the number one spark plug
Sensor 1 is before the catalytic converter
Sensor 2 is after the catalytic converter
Bank 1 Sensor 1, would be the same side as the number one spark plug before the catalytic converter.

In the past, I've owned a lot of cars that were... iffy... when smogged. Here is the list of what I've done in the past. A lot of these steps are only marginally effective, but there are times I've squeaked by with a margin of 1%, so I think every bit counts.
Make sure no error codes were stored in the ECU. In some places, an illuminated check engine ...

I am assuming that you are in NC based on your profile. You can obtain a wavier if you spend at least $200 I will list the rest of the requirements at the end of this post.
I am leery that the catalytic converter is bad, the ECM (the cars computer) uses the post cat O2 sensor to determine cat efficiency and if it's bad as they said it could cause the ...

I am a GM mechanic with 25 years experience working on GM vehicles . I recently road tested a 2011 Chevrolet Cruze with a clicking noise from the right rear while braking . After having the rear drums off a couple of times, I found that the Gray grease installed at the factory on the rear backing plates had been missed in a couple of spots. The grease was a ...

Returned from dealer - this was their report:
"clicking" noise from the R/R of the vehicle when slowing down. The technician road tested the vehicle and verified the concern. Found the rear brake shoes grabbing the drum causing minor grooves in the drum, also the technician found some grease on the backing plate. Cleaned off the grease and cleaned the brake ...

Instructions here. The canister is under the driver's side passenger seat and you need to jack the vehicle up (secure with jack stands) and remove the nearest wheel. Remove tubing, electrical connector and one bolt and it comes out. Once out, you can replace the whole thing or hopefully just replace the valve. Sounds like something I could do on a ...

If the sensor was replaced and you still have problems, then it's either the sensor, the sensor's circuit, or the ECU. Since it's a new sensor, I would check the circuit. If the mechanic it is at cannot do this, then your best bet is to head to a Nissan dealer.
The current mechanic will likely need the factory service manual for this model to properly check ...

Disadvantage is that tampering with emissions systems makes a vehicle no longer street legal.
Other than that, it probably won't hurt anything at all.
I don't see how removing EGR will increase power though. EGR closes at high power settings anyways. The gain would be entirely from some other feature of the racepipe (perhaps it's bigger). The fact that ...

A smoking engine is going to ensure an emission test failure pretty much anywhere these days...
Can you see the engine smoke when it's idling for a while and/or when you rev it?
Worn piston rings certainly would a good reason for a smoking engine, but it can also be something fairly simple like worn valve guides or worn valve guide seals. Either way you ...

These two links give some diagnostic information on catalytic converters and O2 sensors:
Diagnosing 02 sensor
Catalytic converter causing performance problems
If the 02 sensor is working properly and thus properly condemning the catalytic converter, one option is to have an exhaust shop replace just the converter. The factory exhaust pipe with the ...

This sounds like it could be brake pad material on the disk.
If you brake from a fairly high speed down to a stop (e.g., highway speed down to a red light) where you have to sit, foot on brake for a significant period of time, you're holding the brake pad up against the hot disk. That pad material is sticky (on purpose - you want to slow down, right?) and, ...

The check engine light and rear wheel clicking are not likely related. Buy a code reader, or take the car somewhere the next time the check engine light comes on. Pulling the code will give you a much better idea as to what the problem is.
For the clicking, you could jack the back up and rotate the wheels while listening for noise. Maybe then do the same ...

There is a chance your 300E has a Bosh Jetronic fuel injection system. These need their own servicing techniques. Key points are:
new injectors would usually be a good idea
the air path from the filter to the manifold needs checking for leaks as the Jetronic system doesn't like vacuum leaks
how old is the catalytic converter? If it's original, perhaps a ...
