Question about 2006 Nissan Altima
I got the catalytic converter fixed last year. It was about $1700+. I also changed the muffler and got a new one. However, after the new catalytic converter was put in, I notice that sometimes the car gets really hot around my feeet righ where the gas pedal is or the brake. It's not burning me or anything but it concerns me. Why is it like this? Any idea? Not sure if they didn't close the sensors or if they removed the metal sheet that goes between the engine and the inside of the car? Just wondering. It has gotten better since last year but I would feel safer and more secure without this happening.
The most likely reason is when the new cat was installed, the mechanic did not reinstall the stock heat shield that protects the floor from the excessive heat of the catalytic converter. the heat shield either mounts to the floor underneath the car, about the converter, or mounts directly to the converter. Another possibility is that the heat shield was integral to the converter, and the converter that your mechanic installed was a cheap version that did not come with the required heat shield. Either way, I would suggest you try to get the problem resolved, as excessive heat from the converter could cause a whole host of issues.

If that is truly what he told you then you need a second opinion. You can't foul a fuel injector. The computer won't tell you there is water in a cylinder, they aren't that good. Did he give you a print out of codes or anything? You could have some bad fuel in the tank since you said it gets worse when the fuel is low. Get a second opinion or look at your paperwork from the first guy and tell me what he really said.

Do you have a check engine light with this?
What can happen is a code has caused the engine to protect itself. For example in a low coolant situation when the engine heats up too much, the engine can Knock causing an Engine Knock fault.
If that occurs you will recieve a fault for each of these items. Fill the engine with coolant. Then reseting the code will let your engine accelerate normally.
