Question about 2005 Honda Accord 2.4 LX

Open Question

What are the symptoms of a stopped up catalytic converter?

The car accelerates fine when it is cold, but once the engine warms up the engine acts like it has a stopped up fuel filter when you try to accelerate. It accelerates fine if you slowly push down the pedal.

SOURCE: 1994 honda civic 1.5 16v stalling after pressing accelerator from idle

Another place to look is your IAC, or Idle air control valve. It is bolted to the back of the intake manifold, and can be removed and cleaned. It is usually the cause of most Honda Idle problems.

First check the fuel filter, fuel pump and fuel pressure regulator to make sure they are all functioning properly. Also, check the catalytic converter to make sure they are not plugged.

2004 Blazer runs normal cold start, plenty of power. Bogs down after warm up, diminishing power, won't go. Catalytic Converter? What is temp sensitive could bog engine down?

The Catalytic Converter is one possibility, but not likely. If when the truck bogs down, and stalls out, this could be more related to a fuel pump issue. If on your truck the fuel pump is located inside of the fuel tank, then once the pump heats up, this would happen. Acting as though it's something electrical, but it's really not.

Car has little acceleration after driving awhile

Hello julieta_barr: My name is Roger and I will help you. If this happens after the engine warms up and the engine runs fine cold. I would look at the catalytic converter as the problem. When the converter is damaged the engine can run great cold. As the engine warms up a bad converter will close off and choke the exhaust down. Top speed will drop off dramatically. I would also replace the fuel filter as this could cause a problem. The converter can be checked but you need the equipment to do it. Should you have any questions please just ask. I will be glad to answer them for you. Please rate the quality of the answer as this is how we know you received the correct answer. Thank You for using FixYa. Roger

Acceleration problem when temp at 50-70 deg. C

Jack the car up on the drivers side and block it for safety. Now look under the car at the transmission. If there is a block with an electric switch mounted to the trans(look right where the trans bolts to engine) then you have a shifter lock out that limits the rpm's until the catalytic converter warms up. Just disconnect it and you should be fine.

1996 Chevy Express 1500 w/5.0 bogging only when warm.

The cylinder 7 misfire is likely a symptom of the problem, not the problem itself.

Typically, the catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. The downstream 02 sensor reading should be fairly steady. Typically the P0420 code triggers the check engine light if the readings of the two sensors are similar. This is indicative of (among other things - such as faulty sensors in the "emissions loop") a converter that is not working as efficiently as it should be.

I do not believe that it is a problem with a valve/head gasket or cam.
