SOURCE: Stalling and black smoke

Your truck is fuel injected . Black smoke indicates a rich fuel mixture. This could be caused by numerous items. A faulty sensor, a faulty injector, a misfiring spark plug are some of them. To really zone in on the problem, a computer diagnosis is required to note sensor readings, and repair as necessary.

SOURCE: Exhaust pipe rattles when car idles. Had muffler

Check the heat shield on the Catalytic Converter, after a few years they start to rust off and rattle. Crawl under the Pathfinder and bang along the Converter and muffler area and see where it's coming from.   Good chances are, it's from the heat shield since you already had everything changed from the Cat back.
Good luck and hope this helps.

What is causing engine running too rich when idling


I would check to see if there is a restriction in the fuel return lines. Also the o2 sensor might be lazy.

What is year--make--model?
Are you losing coolant? The white smoke may be coolant in the combustion cylinder, possibly caused by a head gasket problem. If head gasket problem, fix that first.

With idle issues, clean/check anything that has to do with idle air system. Any applicable trouble codes?

If this condition happens first thing when you start the car, especially in cold temperature(s) climate, you have nothing to worry about; this is normal. It is simply water vapor- a normal combustion byproduct.

Here's what happens: the exhaust manifold is attached to the engine.

The exhaust manifold takes the exhaust from each cylinder and combines it into the manifold.

The exhaust gases then pass through the exhaust pipes to the various components of the after-treatment system which include the exhaust gas recirculation (EGR) system, catalytic converter and the muffler.

Before the gasses reach the catalytic converter however, they pass the oxygen sensor. The oxygen sensor tells the on-board computer what the composition of the gas is, and diverts some of this gas back into the engine via the exhaust recirculation system.

The recirculated exhaust helps keep some of the toxic gasses from entering the rest of the exhaust system.

The recirculated exhaust gasses also cool the engine cylinders, which in turn, decreases fuel consumption.

Depending on the year, make and model of the vehicle, the exhaust gas recirculation system may have an electronic EGR valve or a vacuum-operated valve. The electronic EGR valve has additional parts, including an EGR solenoid.

If the EGR system does fail, you may hear a ping and the vehicle won't pass emissions. If the EGR valve fails in the open position, the vehicle will not idle properly.

When the exhaust gases reach the catalytic converter, it reignites the gases that are not burnt in the combustion chamber so that they are not emitted into the atmosphere.

The catalytic converter creates a chemical reaction, burning the excess gasses and toxic by-products from the engine combustion process.

And in so doing, the catalytic converter changes carbon monoxide and hydrocarbons into water vapor and carbon dioxide (which is its main function.) And that is what you are seeing coming out of your car's tail-pipe!

Warmest regards.

The engine is running very rich that is why the exhaust is emitting black smoke. The engine needs a tune up so the air fuel mixture is correct.

White smoke coming from tail pipe with water when idled


When you first start an engine when it is cold, it is mormal the exhaust pipe will emit water vapor (white steam) and water until the engine reaches running temperature.
If this problem occurs when the engine is hot and been running a while then you could have a head gasket problem, especially if you have to top up the water in the radiator frequently.
You need to get a mechanic to do a compression test on each cylinder to determine the exact problem with the engine.
