At the time you made all the above repairs, did you replace the "throw away" turbo charger? The turbo charger commonly sucks oil, and it is not repairable.

Run it without the inner & outer air cleaner. If it isn't the turbo, run the injector cut out test. If the injectors are ok, then you need to replace the injection system hydraulic pump, which is also unrepairable.

05 Forenza green clock light keeps flashing. Also catalytic converter overheating causing heating and burning wires


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.

The Cat got to much unburned fuel and that is what made it get glowing hot. So you have 2 oxygen sensors, one before the cat and one after. If the one after has the same reading as the first one then you get a check engine code.

Won't start at times


Cat. converter in your exhaust may be clogged, building up backpressure as the engine runs. Pressure slowly releases over time, allowing your engine to start after sitting. A clogged catalytic converter has been known to get so hot it will glow red, espically in the dark.

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.

Engine running very rough and exast under car very hot.


DISCONCT THE EHXAUST BEFORE THE CAT AND ROAD TEST.
A GLOWING CAT HAS MOST LIKELY FAILED.
BUT LOOK FOR OTHER PROBLEMS THE MAY HAVE CAUSED THE CAT TO FAIL.
