if the check engine light is on go to auto zone (or some other places) they will read the codes for free. my guess if your car has over 60000 miles or so that you have another coil out (yes these cars have either 6 or 8 coils one for each cylinder) check which coil was replaced (ie cylinder number). the code will usaly say something like cylinder x missing detected. if no code or no light you might have to wait until the problem continues until the puter sences the problem. i have replaced all of my coils by 90k miles. cheers If the valve cover gaskets are leaking oil down onto the coils and plugs, this can cause the coil(s) to fail and the plug/cylinder will misfire and make the car run weak and rough. My 2001 Base V8 is in the shop now for a valve cover gasket replacement job, 75000 miles.

Check to see if catalytic converter is stopped up,a clogged fuel filter can cause it to go bad .

No, it merely reduces pollution. It does not come into play until the gas has already been burned.

Should you cut off the catalytic converter? No. But can you and will SOME vehicles actually benefit? Yes. It is illegal to remove any emmision control device from your vehicle in most if not all states. For countries such as Mexico where it is not illegal, some vehicles without downstream Oxygen sensors (after the catalytic converter) it can have some benefits. It is really the same benefit as a free flowing exhaust. Modern (97+) cars already have a free flowing design catalytic converter so there is no benefit to doing this.

Catalytic converter. 9 out of 10 times when a car runs fin cool and stalls when warm, this is the problem.

User Avatar

There is no reason to do this. Modern catalytic converters do not restrict your exhaust flow. All you will gain by breaking it out is a check engine light coming on that will never go away. If your check engine light is already on for a catalytic converter problem removing the honeycomb will not fix it.

take the catalytic converter off. you can punch the guts out of the converter so you have a pipe to got back on the exhaust.

IS THE CHECK ENGINE LIGHT ON? IF SO, DOES IT HAVE CODE 0420? IF THE CATALYTIC CONVERTER IS BLOCKED, THE ENGINE WILL RUN FOR A FEW SECONDS AND STOP BECAUSE THE EXHAUST BUILDS UP TOO MUCH BACK PRESSURE.

User Avatar

the P1163 code refers to the Primary Oxygen Sensor in your car, which is found before your CAT, or catalytic converter. The code is "Primary HO2S (No. 1) Circuit Slow Response" I have the same code on my 98 Honda civic, but have already replaced the sensor, so i am in quite a situation. My check engine light WILL NOT GO OFF! but i hope i helped you if you havent replaced your oxygen sensor yet

User Avatar

yes, but it is illegal and i do not encourage it becasue your engine light will stay on, but if your converter has already damaged your engine, it is to late and you need to replace the engine. this happens because the pre cat or pieces of it get sucked up into the engine damageing the cylinders

The current version of Total video converter is 3.60 already.

Blown fuse or wiring defect for the bulb you have already replaced. You have replaced the wrong bulb. The new bulb was defective.

User Avatar

I guess it would depend if the replacement part is a bolt in or a weld in, either way it should take about a half hour to a hour of shop time.

User Avatar

I have just submitted this question and I wanted to let anyone who can answer this to know that I have already replaced the fuel filter, plugs and wires. My next attempt will be the catalyptic converter.

User Avatar

You have spent quite a bit of money and still have the problem. Obviously the converter and the O2 sensor did not need replacing. Take the car to a professional who actually knows what they are doing, and stop throwing parts at the problem.You have spent quite a bit of money and still have the problem.

the sensor(s) are going to be located near the catalytic converter. you probably have two...One located before the converter and one located right after the converter. you can use either a 20-22 mil box wrench or a really deep socket...most auto stores carry a specific tool for it. You just unscrew the old one pop in the new one...these sensors usually have some anti-seize on them from the parts store already so no need to add any if you don't already have some laying around somewhere.

The horse and buggy was replaced by the automobile. Trains already existed before the automobile.

User Avatar

Sorry but, you don't know this one. There are 3 one on each manifold and one on the top of the catalytic converter. There about $200 each at auto store. Find them cheaper online. There are two, one right before the catalytic converter and one right after. The computer compares the two, and adjusts fuel accordingly. The front one runs a little hotter and tends to need replacing more often. However, save yourself the headache and change them both at the same time. Heck, you're already dirty.

Even though you have already replaced the thermostat, there are other issues that can cause your Nissan Maxima to overheat. Your fan may be stuck and not operating as it should.

I have a 1991 v6 and the o2 sensor isn't exactly where all the repair guides say it is. They all say its on the exhaust manifold. If you have already checked there and haven't found anything I woul look underneath the car just before the catalytic converter. That's where mine is.

this is simple, either download a free version of a video/file converter online; or purchase one. or you could just ask a friend to do it for you if they already have a video converter.
