Usa car?
2.0L engine,
the stock car had nice wiring , harness wiring and clamps and works great, until..
but someone hacked yours all up,
why not photo the clock light, no idea at all what that means.
photo it and post .
does clock mean the TIME CLOCK or does that mean the SPEEDO CLOCK warning lamps glow, see 2 photos of me guessing what clock means , on your car.

what makes you think the cat is too hot, do tell.
why.? (sure they do , and is symptoms of rich)
but is normal to get hot, they all do.
the cat can go to 3000F normally, you do know that right.?
my guess is you failed to scan the PCM.
or ask any shop in town to do that.
(if the check engine light is on get car serviced)
same for too hot cat.
same for misfire, makes cat hot too.
same for sure if the CEL lamp flashes
the operators guide tells you that that means overheating the cat, as designed to do.
on all cars.

the burned wires, are hacks.
Hacks as in letting unskilled works touch car.
they hack it up bad. (or butchers)
the weak wires do not get near the cat. on a stock car.
then come to the 02 at 90degree angle,
the o2 wires actual pig tails wires are high temp special wire, very high temp..

but not the harness side, they will melt if hacked , hacker cut the clamps up and allowed the soft low temp harness side hit the cat or exhaust
He did a hack job
he fail to put it back as he found it, sad no?.

the engineer of your car designed the cat and wire
to be ok, even if say , then engine thermostat failed cold and the fuel mix goes gross RICH.
that is all part of the engineering done !!!
see those cat shields, they also must be in place.

then the CAT gets way hotter , why hotter, this is its job.
it's job is to burn up (catalyze ) all that wasted rich fuel.
to keep the earth green. (includes lungs)
it burns HC, Hydrocarbons and gets even RED hot.
the problem is 2 fold
bad wiring
and not scanning the PCM.
2 fold.05 Forenza green clock light keeps flashing. Also  - 8602ef0b-55d4-45a9-bd9d-fac3a88e7278.jpg26415985-nsabpuc2opng0ihlktbwx0wi-5-2.jpg

SOURCE: do I need a catalytic converter

Yes but there could be other causes. A sticky fuel injector, bad fuel pump etc. Other signs of a bad catalytic converter are a smelly sulphur exhaust, a very hot exhaust throwing heat from the middle of the car. Unless there's a lot of miles on your car, I'd be surprised if it were a bad Cat. Hope this answers your question. Best of luck.

SOURCE: need to replace catalytic converter heat shield

I just took mine off to keep it from rattling, and bought a heat resistant header tape and placed the tape right over the Catalytic Converter on the body it self. Good luck and keep me posted if you have any more questions.

I have a 2002 Dodge Stratus 3.0, when accelerating the engine chugs and engine light flashes. I heard it's a bad catalytic converter, is this true?

A plugged converter will cause a NO power situation where the vehicle is unable to expell exhaust gasses and cause poor acceleration. A flashing engine light is the result of a misfire. ( spark plug/coil/injector/wiring ). The engine should still be able to accelerate but will have a noticeable hesitation while doing so

Problems with '05 GMC Sierra, Standard

Typically, a flashing light is more serious than a solid check-engine light. The flashing light is meant to alert you that you may have a misfire in your engine that will cause catalytic converter damage if you leave the problem unresolved. Replacing a catalytic converter can be costly, so have the engine checked as soon as possible by a certified mechanic.

Check engine is flashing. Checked water level and found it very low. Added water but no coolant. Still flashing. Will lack of coolant cause Check Engine light to flash ?

No. a flashing check engine light means that there is a serious possibility that the catalytic converter is in danger of getting damaged. If you are losing coolant (and i am guessing that your engine is overheating) you most likely have a blown head gasket or a cracked cylinder head. And because of that you are getting a large quantity of coolant on the exhaust system, which can ultimately damage the catalytic converter.

2000 jeep cherokee water pump, radiator, thermostat, coolant system is it is overheating again....hard starting and idles very rough...I think the catalytic converter may be...

the main symtom of a bad converter is. you can push pedal to floor and only go about 15 mph, if it is clogged up. the car will idle well but no power at all. the fist thing is overheating usually from misfiring spark plugs, and burns out the mechanisms inside. Catalytic converters are not designed to handle the heat of burning fuel; when fuel starts to burn in the converter, it can cause a great deal of damage to the converter and the rest of the exhaust system. One of the noticeable symptoms of overheating in the converter is a significant loss of power from the engine.

Have had two catalytic converters go out in last 8 months

Catalytic converters should last the life of the vehicle. usually they are damaged be a poorly running engine. most common causes are lean misfire causing unburnt fuel and air to get into the convert and ignite there. coolant or oil burning. engine running too hot (lean) overheating converters.

was it the same converter that went twice? did they change them at the same time? where the pre-converters? is the engine light on?
