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 ...

The diagnostic trouble code is not to be looked at as a root cause of the system failure. (example. Replacing a blown fuse is NOT a solution) In all cases there are multiple components that can cause the same code to trigger. For instance, a possible vacuum leak, or EGR problems, and even a PCV issue, could all show o2 sensor readings with tendencies towards ...

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 ...

Yes, it will probably be necessary to fix the problem in order to pass emissions requirements. The secondary air injection pump on the Beetle is apparently used to accelerate the transition from cold start to hot catalytic converter operation. Without this system, it will take longer for the catalytic converter to reach operating temperature. The ...

With the check engine light on, the car is going to be running a fixed set of parameters from the Engine Control Module. For instance Fuel Pressure will be held at max pressure and timing and spark adjustments (if done electronically) will not retard or advance. One of the reasons this happens is because the Engine Control Module is not recieving all of ...

The first thing to do is too take the EGR out of circuit. A quick and easy way to do this is to cut an old metal oil can(its thin enough for scissors) so you have a piece of the can that will fit between the bolts of the EGR. Tighten the EGR bolts up with the can acting as a gasket. Now try watching the MAF sensor voltage as you rev the engine sharply and ...

Do not put your bare hand over the tailpipe, it will get burnt. If you cannot hear an exhaust leak, puff puffing, you can pressurise the exhaust system with a rag over the tailpipe to make an exhaust leak more pronounced and tracible. The downside to this is that you can destroy the catalytic converter, so it is really not a good idea to do it. The way ...

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 ...

In terms of possible root causes for failure, the following scenarios are likely culprits for a cooling system to run too cool: A temperature sensor that's reporting lower-than-actual temperatures due to issues like drift/fouling/calibration. A sticking thermostat that is flowing more coolant than necessary to maintain 176 °F. Really cold ambient air ...

Every car's OBDII diagnostic is going to be slightly different (between manufacturers, anyway), but you should not be dismayed. You have five days until you fail your test, which is more than enough time to ensure your vehicle will be OBDII ready. This of course, does not mean if there is an underlying problem it won't cause you to fail for a different ...

Considering on this website they say you can figure out the amount of CO2 emissions per km based on the fuel mileage, I'd suggest they are saying the rate of emissions is proportional to the MPG (given their constant). This makes sense to me because there are so many carbon atoms in a gallon of gas. When burnt (correctly), the CO2 emissions are going to be ...

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 ...

They might have bent a shield, and can really only be heard when going slow. Sometimes this happens if a tire hits them while removing them, or during installation.

Newer cars (1996 and later) have additional catalyst agents than the old cars had. $100 sounds like one of the old car cats. $500-1000 is more in the ballpark where the newer cats are typically found. Will an old cat keep your light off? Perhaps. Perhaps not. Is it a legal replacement, no, not from what I remember of the federal code.

Barring an accident which might damage a canister, it should last the life of the vehicle.

To perform an OBDII Driving cycle do the following: Cold Start. In order to be classified as a cold start the engine coolant temperature must be below 50°C (122°F) and within 6°C (11°F) of the ambient air temperature at startup. Do not leave the key on prior to the cold start or the heated oxygen sensor diagnostic may not run. Idle. The engine must be run ...

This is by far the best video I've seen which gives two ways to tell if your catalytic converter is bad. In a nutshell, Eric the Car Guy uses two methods to diagnose a bad converter: He uses a scan tool which uses live data to do just what you are looking at. He is checking to see how the downstream O2 sensor is behaving. Basically it should be fairly ...

Looking at the description of the California O2 sensor for your car, the only thing different on it (besides the internals) is the electrical plug. The wrench which you tighten it down with is 7/8", which means the sensor bung should be the same size as well. I don't think there is any real external difference between the California and non-California ...

Thanks for your advise, Allan. Got the car up on the lift, and was greeted with a nice large hole in the exhaust - large enough to fit two fingers into, and one of many. The botched weld job didn't help, either. The exhaust was replaced with a stainless steel version (as opposed to mild steel), and a full engine flush was preformed - cleaning the ...

Sadly there was no headway to be made and I sold it for scrap value. The garage wanted £700+ to dismantle and inspect the engine. The guy said the last time he'd seen that issue, it turned out to be a worn piston ring. I suggested that surely that ought to cause compression failure which was not evident in his inspection; he agreed, but that was what he ...

In my experience, yes. Unfortunately, these cheaper alternative catalytic converters are often not efficient enough for the modern systems in cars. One of the important elements for catalyst efficiency is platinum - that is why good ones are often expensive.

What's the return policy? If it doesn't work, can you get a refund? If so, you might give it a shot, if you're not paying anybody to put it on. If you are, shop around for the cheapest estimate where they'll guarantee the repair. You don't want to pay for labor to find out the cheap cat doesn't work. A factory part should be guaranteed to work, but that will ...
