Car Maintenance : Can a Bad Catalytic Converter Make a Car Overheat?

[thecheesburgler]

Overheating is most likely caused by a dead fan, thermostat or something else in the closed cooling system This is highly unlikely.

[drumtalk]

I am trying to clean out my catalytic converter. In order to remove my catalytic converter I have to remove the whole exhaust system from the engine and towards the back. Instead of doing this,. Can I remove the oxygen sensor the one that is sitting in front of the converter and use a flush gun tank like the ones they use to flush out a/c system contaminents from the line with lacquer thinner? Do you think this will clean the system if I do this a couple of times?

[dshiz16]

one more thing is there a certain thinner you should not use?

[dshiz16]

can it cause a random misfire? P0300... change spark plugs, cables, ignition coil cap/ rotor, fuel filter, pcv, even downstream O2 sensor. Im tired of throwing parts!!!

[oerllikon2]

FOR RECREATIONAL USE OR USE WHERE ALLOWED: You can cut the cat off and rig the o2 sensor up so it gets hot but it gets fresh air on the outside. Apparently it works on the XJs with the 4.0L engines. Im trying it on mine, im getting overheating, and I got a code about a bad o2 reading after the cat

[lozphg]

does the car have to overheat for it to have a bad catalytic converter???

pm me back please

[Rushfan32935]

@lozphg Not always. Sometimes it can be a problem with the EGR system or a faulty Oxygen sensor (which is what my problem was) among other things.

my vehicle has a clogged catalytic converter and its still running. It does sometimes have a loss in power but the mechanic said that its not a major problem right now. I am going to get a replacement.

[The18Jake]

@kargmeister1337 it can be a major problem, I've had mine get so clogged that my car wouldn't even stay running. I still haven't replaced them but I've cut the exhaust off after the cat. (It was also clogged)

[Mrchip61]

i have a f150 04 check engine light is on scan truck says catalytic converter running lean is there something i can do without buying new converter

[cooolcars]

@almarai185

100% agree with you. they are a waste of time.

[changomoreno13]

[jayguy173]

@changomoreno13 meters you put on the tailpipe

[alfaandomegaagain]

Don't do drugs.

[spam420rice]

I have a 3rz engine has no power and whines loud full trottle, blows off egr hose..

[pigdisposal]

i would change out the cat every 2 years if you have the money because its gonna kill you on gas, other than that its gonna be hard to destroy anyhting.

[rockthedrums4life]

dont listen to just anyones information as its just a guess ,i just found out today the reason my car is not running more than 30mph and hitting gears hard its because my catalytic converter melted and clogged up my exhaust,if u dont have to go through emissions put straight pipe.its better for your engine.lie guys says also..a half bad one it bad for you

[6899999]

2 things to consider:

1 reason to have a catalytic converter (CAT) is to reduce harmful emissions from the exhaust of a combustion engine (Global Warming Against the LAW). 2 reason is today's cars are designed for optimum performance by virtue of their engine management, it is done by your ECU reading emissions form your CAT and the O2 censor, depending on your car year and model, removing the CAT can lead to unbalancing of settings to the ECU, and may cause a reduction in brake horsepower.

[yellowandbluegroup]

I think my catalytic converter is clogged up it just started rattling 2 days ago . but i dont have money to fix it right now . if i keep driving it casualy . Should i be in the clear?

[magnaflowedramx4]

I ran discount gasoline for a long time. My CAT clogged up and almost trashed the whole engine so I had a new exhaust system installed without the CAT. My truck never ran better

[bmlaabul]

i have a question if you do not mind , i have a ford mustang gt they told me for extra horse power u can remove the catalytic converter, so do u recommend doing it or not thanks

[fromcanada38]

@bmlaabul

[hardcorejunky1000]

Heh, wrong, I got an aftermarket cat/delete test pipe and had it for 3 years, never ever had it over heat on me once. I passed emissions with flying colors too. If you want to know what i got, Ill let you know so you wont have this problem.

[Rosman1974]

Lately my car started jerking when I am pressing on the gas pedal. Like when I come to a complete stop and start to go it does it! Also it does it when I try to increase my speed on the road! It even feels like it want to die on me! It is a 2000 Chevy Malibu and has 94,000 miles on it. I guess its time ofr a new car but I use it only for work. What do you think the car's problem is?

[roninsparta]

This sounds like symptoms that can be ameliorated by a simple engine tune-up. Because there's a obscurity in your description of the affliction with your vehicle--- but if the following were true of your vehicle(upon depressing the throttle/acceleration/gas peddle; your car stalls/hesitate to accelerate right away;then my hypothesis would be that there's a misfire in your engine's firing order or that one of your cylinder's inoperable).

1 its an american car and 2 your cats are clogged
