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 ...

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 ...

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.

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 ...

A couple thoughts on things to check are: Failing idle air controller Sticking EGR valve

Turns out it was just a spider laying eggs in the valve. Asked the dealer to try blowing it out with the compressed air. Been working ever since, no problems. Apparently the spiders like the smell of inside there and this is a somewhat common problem documented in the service knowledge bases for this car and several others.

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 ...
