The cat. should not be plugged on a truck that is only 3 years old. might be faulty ignition component(s). Check inside distributor cap for moisture or metal particles. dim or turn off lights in garage and spray a fine mist of water from a spray bottle over cap and spark plug wires take note of any arcing of spark. this could indicate faulty plug wires. GOOD LUCK. If it is the cat. that is bad on a truck this new it is a symptom of a bigger problem.

Obd light on, idle rough, smell, no throttle


The obd light with tell specifically what it is, is it gas or rotten egg - the latter means catalytic converter, gas smell probably flooded or not firing on one or more cylinders, need more details. Also, if the light is flashing it's warning of catalytic damage - raw fuel hitting the cat, smell could be heat from cat trying to burn off raw fuel,it will glow red hot.

2000 jeep cherokee 4.0......new water pump, radiator, thermostat, coolant system is full....now 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.

Start car, runs good, drive for a mile and instant loss of power, power fluxuation, rough idle, accelerate out of it at idle, idle good then when you accelerate or try to put in drive it dies


Have the codes checked and post them to better give me an idea it may sound like it could be a clogged up catalytic converter but checked the codes if it coincides with what i just told you then it is the catalytic converter let me know something thanks.

I have a 96 Honda Civic HX. When I am at idle the car starts to shake and the rpms fall almost to zero. I took the car to a mechanic and was told that I need a new Catalytic Converter and the EGR ports...


Yes and No. The EGR can cause the car to idle rough and or stall. I am assumeing the check engine light was on and set code for EGR and Catalytic Converter. If the engine isn't running right it is possible the cat won't work right due to improper air fuel ratio that the EGR is causing. To do repair proper the EGR should be fixed then clear codes and see if the code for Catalytic Converter. There are other reasons that would your car to idle rough or stall I am just assuming that this mechanic got codes or tested the EGR right.

Engine has no power, Idles in Park a little rough and in drive with the foot on the brake idles rougher. Have replaced fuel pump and filter as well as catalytic converter and O2 sensor.


THE FACT THAT IT GETS WORSE WHEN YOU STEP ON THE BRAKE INDICATES THAT YOU HAVE A VACUME LEAK.IF YOU DON'T FIND A LEAK,START PULLING PLUG WIRES OFF ONE AT A TIME TO SEE WHICH OF THE PLUGS HAVE FAILED,[THE ONE THAT YOU PULL OFF THAT DOES NOT CHANGE RPM IS THE ONE YOU'RE LOOKING FOR].

Your catalytic converter is plugged up,  If you check the exhaust output at the tailpipe you will find it restricted.
