Depends on what is wrong. Hole in the muffler or converter then NO, do not drive this vehicle as there is a danger of carbon monoxide entering the cabin and causing you to go to sleep and have an accident. It has no smell, or taste so you will not know it is present.
Clogged converter is also a no, no. This will cause engine damage. Bottom line is get it repaired whatever the problem.
Something is wrong with the catalytic converter.
Go to a muffler shop to check the converter to see if its clogged. Also what is meant by the word straining.
If your car knocks, grinds, squeaks and makes other unholy noises, it may have a bad muffler. A muffler is basically a series of tubes and chambers located under the car at its back end. Mufflers quiet the noise made by the engine and reduce noxious emissions. If your car's muffler isn't working, you're polluting the atmosphere with fumes and unpleasant noise every time you go for a drive.
I would suspect a plugged up catalytic converter
yes can cause poor exhaust flow and cause car to set codes for cat. converter, o2 sensors ,or fuel trim
Because something is wrong with it.
cat. con. honeycomb material may have gone downstream and is plugging the muffler. this happened to me; had to get a nerw muffler.
Your bad muffler might be part of the reason your check engine light comes on. Usually, your bad muffler causes something else to go wrong and that causes your check engine light to come on. Problems cascade.
It the caralytic converter is clogged you may do serious damage to your engine. At the very least you will get very poor mileage. I would repair this before taking a trip of tha distance. Common sense should apply.
well your u-joint is mostly just old and needs to be replaced. o you have something wrong with your 4 wheel drive. if something is wrong with your 4 wheel drive i would take it to a pro that knows what hes doing
I think what you are seeing is your muffler leaking condensation from a weep hole. This normal and will stop after your vehicle has reached full operating temperature.
It might be dirty injectors. Diesels are sensitive that way. Take it to an injector specialist.
