99 I LS 400 replace front converter right side still glowing red hot lack power


the cat glows, for these reasons
engine bank 2 is very rich and you have lots of air (oxygen)
present, when the right bank misfires that too blows. oxgen to the cat and it glows red hot.
fix the EFI fuel trim on bank 2,
use a scan tool to check trim, and do the diagnosis.

Trying to locate o2 sensor and massive air flow sensor on 2000 taurus


you didnt say what motor you had, but heres a few tips

the MASS (not massive) Air flow sensor -MAF is located between the air filter assembly and the throttle body

the O2 sensors are located either in the exhaust manifold and/or the exhaust pipes, many times before and after the cat. convertor.

anyplace you are getting your replacement parts from should be able to tell you right where these components are located

Catalytic converter stopped up. Pipes got red hot. Replaced Cat. Conv. car runs good, then started random misfires, pipes got red hot again. What is exhaust part that is downstream of Cat. Conv. could it...


If the exhaust system was plugged the engine wont run, normally. It will start and idle until the back pressure is such that it can't take in more air/fuel mixture and then stall.

After the converter, there may be a resonator, and then the muffler. Is any exhaust flowing out of the tail pipe? You might try hooking up a scanner and see what your oxygen sensor(s) is/are doing.
Also, scan the MAF(mass air flow) sensor assembly.
Sound like the engine can't breathe, and its getting to much fuel.

The vehicle was put on a diagnostic machine for loss of power and it coded the o2 sensor, and the mass air flow, and EGR valve. We put a new o2 sensor in and cleaned the mass air flow. It ran, but no...


no-- but could mean that the O2 sensor is not correct
it is a common misconception that all of the oxygen sensor are the same
the fact is that even they are known a oxygen sensors there are 2 completely different units
the sensor in the exhaust manifold before the cat converter is in fact a heated oxygen sensor and it's function is to report the exhaust composition so that the ecm can adjust the air/fuel mixture
the other is an o2 sensor located after the cat converter and fine tunes the system after the cat converter has done it's job
if the cat converter is faulty , the o2 sensor will try to have the ECM correct the mixture
the loss of power if it is a cat converter comes from a blocked exhaust system and that is most evident at high rpms or under power
