Lower intake leaking vacuum. Seven weeks later I went in for routine oil change, and told them of rattle. After four hours of waiting, I was told it now is the front converter, saying that when the rear one blew out, it probably damaged the front one.
I haven't fixed it yet. There are three catalytic converters in this thing, scary. I was told not to wait too long to get 2 replaced because it could cause damage to the one I already replaced and the 3rd one. I am afraid what is expenses are coming next; I have heard horror stories about the transmissions in these Escapes.
I could buy a new car for the money I am putting into this one. I took it in and they said it was the catalytic converter, it was clogged, they changed it, then six weeks later, same thing, would not accelerate, I was stuck on the highway heading to an appointment, once again it was a clogged catalytic converter, this is when I found out that the truck has THREE catalytic converters This truck has been a good vehicle, but when something needs to be repaired, it's very expensive.

Its main job though is to scorch away all of the unburned particles that are dirtying the exhaust gases that escape from the engine. The operating temperature of the catalytic converter is usually between and Fahrenheit, which is the temperature that it reaches as you drive the car.
The compound within the converter consists of precious metals like palladium, rhodium, and platinum. Once the catalyst loses its ability to burn the remaining hydrocarbons from the exhaust, a nasty smell could ensue, or you might notice frequent misfiring, a rough run, and the Check Engine light might come on. A clogged catalytic converter can also lead to staling or a failure to start, as well as the engine light coming on. If things get worse, the surplus blockage will create unwanted pressure, which in effect, can lead to interior engine damage.
Cars that have tailpipe emissions often have poor air quality, and that adds to breathing ailments and environmental pollution. What you smell is the accumulation of all the things that were not burnt off by the converter. Fuel economy also suffers when the catalytic converter gets damaged because now the car has to work twice as hard to perform normal tasks, thus requiring more fuel than usual. So if your car keeps running out of gas quickly, then you might have a problem with the catalytic converter.
In the worst-case scenario, a defective catalytic converter will limit the exhaust flow and will result in rough running and even total engine failure. There are varying types of diagnostic methods that mechanics use for different levels of converter failure.
Should the check engine sign flash on to reveal catalytic converter failure, then you should follow the diagnostic procedures as set out by the manufacturer to determine the cause.
Replacing a catalytic converter is a rather complex task that requires the use of specialized tools; hence it should be left to the professionals.
For example, the mechanic has to use a power saw just to cut the old catalytic converter out and remove it. This has to be done delicately and carefully because one wrong step and the procedure might cause damage to other parts surrounding the converter. Once the old converter is out, the mechanic will weld the new converter in its place.
Sometimes, an obstruction in the fuel like dirt and debris can compromise the efficiency of the catalytic converter considerably. Cleaning the fuel with an appropriate cleaner is one of the most efficient ways that you can use to save the catalytic converter from total damage.
