96' Toyoya Camary There is fuel leaking from the exhaust manifold (where is being pointed).

Several things.
Cracked exhaust manifold, leaking connector at the pipe, damaged exhaust pipe, and so on.
A mechanic should be able to find the leak.

Check the exhaust manifold from the engine bay to exhaust system

It's exhaust manifold. There are two manifolds, the intake manifold in the valley between the cylinder heads, and the exhaust manifolds, one on each side of a v figured engine.

And, yes, a leak in the exhaust or the intake will make it run lean. If the leak is close to the engine, it can do harm to the valves, too. There is a gasket between the exhaust manifold and the engine block. Likewise, there is an intake manifold gasket between the intake manifold and the block.

Trouble Code: P0171

Fuel Trim System Lean (Bank 1)

Possible Causes:


Air leaks in intake manifold, exhaust pipes or exhaust manifold.Fuel control sensor is out of calibration (ECT, IAT or MAF.)Low fuel pressure (fuel filter clogged, pressure regulator failure).One or more injectors restricted or pressure regulator has failed.HO2S element is contaminated, deteriorated or has failed.Vacuum hose is disconnected, broken, leaking or loose.Trouble Code: P0174

Fuel Trim System Lean (Bank 2)

Possible Causes:


Air leaks in intake manifold, exhaust pipes or exhaust manifold.Fuel control sensor is out of calibration (ECT, IAT or MAF).Low fuel pressure (fuel filter clogged, pressure regulator failure).One or more injectors restricted or pressure regulator has failed.HO2S element is contaminated, deteriorated or has failed.Vacuum hose is disconnected, broken, leaking or loose.

One of two places the Coolant will escape from! Check all of ur hoses . For soft or swollen ! These engines are notorious for head problems!

bank one upstream oxygen sensor on exhaust manifold bank two oxygen sensor after catalytic converter.tell me what code you are getting.bank 1 sensor 1 fuel system is too rich fuel pressure too high fuel pressure regulator leaking or more than 1 fuel injector leaking. fuel contaminated.check spark plugs if black carbon color fuel system too rich. if you getting code bank 1 sensor 2 check for air leaks in the exhaust system, air leaks intake manifold.look for vacuum lines leaks,look for vacuum leaks pcv valve and hose and make egr valve not stuck open or gasket leak.

02 sensors are located in the exhaust the upstream ones are close to the engine in the rear exhaust manifold (for 6 cylinders) and at the front exhaust (for 4 cylinder). The downstream ones are behind the catalytic converter. Check to make sure the fuel pressure regulator on the to of the engine isn't leaking. Replace the air and fuel filter could be plugged. Check the coolant level in both the rad and the reservoir they are notorious for intake manifold and head gasket leaks for 6 cylinders. There aren't many calibration updates for this vehicle relating to fuel consumption.

There are several areas to check for possible exhaust leaks. i will list them below.

1. Exhaust manifold gaskets - This will be the most common area. There is a gasket that separates the block from the exhaust manifold. these gaskets can fail, thus, causing a exhaust leak at the manifold.

2. Lower manifold gasket(donut gasket) - This will be a possible leak spot as well. This small circular gasket is placed in between the upper exhaust pie and the lower side of the manifold. It basically separates the pipe from the exhaust manifold.

3. Exhaust pipe - The entire pipe can rust overtime, thus, creating small holes along the pipe structure. These holes will cause the exhaust to leak ,thus, filling the vehicle will moderate fumes and causing louder than normal engine sounds during revving.

4. Muffler - This component can also deteriorate to the point that it cannot filter out the noise. It will also cause leaks as well.

You will find the leak in one or all of the areas stated above in the list.

you may have a stuck injector. Des it appear to be running rich, black smoke from exhaust or a smutty tail pipe? let me know

cherry red? you may have a clogged cat. convertor
