1994 Honda Accord very rough idle, bogging, stuttering and

One morning last week, I get in my car to go to class and it starts like it always does and everything seems normal. The night before it was running fine too. Upon pulling out of my driveway, I noticed that it kind of began to stutter, but I pushed down the gas pedal more and as the RPM's picked up the stuttering/bogging went away. It only did that during take off from a stopped position and did that all the way to class, which is about 6 miles. On my way back home, it still did the stuttering/bogging thing, but it was still drivable. Later on, I decided to go to the store to get some fuel injector cleaner, but my car began stuttering/bogging down so badly that it came to a stop on the side of the road. After a few attempts at starting it again with no luck, I popped the hood and noticed the cat. Converter was glowing red hot. I waited 15 minutes for it to cool down and was able to start my car and make it about 2 miles before it bogged down to a complete stop again, but this time there was no waiting and going again. I had it towed home. I probably went about 30 miles with it in the stuttering bogging condition before it wouldn't go no more. I put new plugs in, a new dis. Cap, new rotor button, new catalytic converter, and a new radiator. My old radiator developed a crack in it a week earlier. I am also having a new water pump installed, timing belt, balance belt, valve cover gasket, and fuel filter installed this coming up weekend. I have a feeling none of that will fix ti though because I loosened the fuel line going into the fuel rail and gas was flowing thru it pretty good, so I doubt a new fuel filter will help, but it can't hurt. Also, while sitting in my car and lightly pushing the gas to keep it idling, it vibrates badly and sounds like a 4 stroke motorcycle. It reminds me of a diesel engine the way it acts when im running the engine trying to figure out whats wrong. I checked the CEL codes and it flashed 43, which is a fuel supply system error. When I turn my key to the II position, I can hear my fuel pump kick on for about 2 seconds, so I don't think it is the fuel pump. I've cleaned the EGR and PCV valves, but that only slightly helped the idle when im pressing the gas pedal. Turning the Ac or anything on makes the engine die. It sounds as if it is producing no power. I have an AEM adjustable timing gear and when I advanced the timing 5 deg, it began to slightly run better, so maybe just the timing is off? I have a magnaflow exhaust, new magnaflow cat. Converter, AEM lightweight pulleys, AEM adjustabel cam gear, Bosch 2 plat plug, cold air intake, and Moroso plug wires that are 5 years old. Everything but the plugs and cat. Converter i've had on my car for around 5 years, so I doubt they are any problem. Maybe my wires are old? They appear to be giving spark to each plug because I took each wire off while it was idling and I saw sparks jump to the valve cover from each wire. When I first parked my car in the driveway with this problem, my gas gauge showed 3/4 of a tank of gas, but now it's down to about an 1/8th of a tank for some reason. I see no gas leaks around the gas tank, but maybe an injector is leaking because there is an unburnt gas smell while the engine is running. My 02 sensor is only about 4 years old, so I don't think it would be a problem. My car does burn a little bit of oil because of a bad gasket somewhere that was a factory recall that I never got a letter about. Also, my water pump did go out 2 weeks prior to this happening and that is why I am having a new one put in. There is no sign of water or gas in my oil, but I do notice water slowly dripping from under where my water pump is. I am clueless as to what the problem could be. Has anyone else had a simliar problem or have a solution or any ideas?
Do you
have the same problem?

Hi 94hondaaccord,

When the catalytic converter is running red hot, a major misfiring has occurred and unburnt fuel is getting to it. This would turn it red hot when running.

You need to check what is causing the misfiring.
1. Spark plugs and related parts.
2. Injectors.
3. Compression.
Above are the common reasons for misfiring.

How long have you had the adjustable cam sprockets installed?
Was this
