Question about 2006 Nissan Altima

1 Answer

Why is the area by the pedal so hot?

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.

SOURCE: engine surging , won't accelerate over 3000 rpm ! IS chocking is like is not enogh gas

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.

Possibly your catalytic converter is clogging up. Short of using a thermometer to check exhaust temp's pre- and post-converter (the temp. after the converter should be about 100 degrees hotter that the temp. before the converter), the next best way is to run car with converter un-hooked and see if that is the problem.
Good luck.

Loud muffler noise up front of vehical.what is


If the noise sounds like your muffler, but isn't coming from the area of your muffler, then you have an exhaust leak upstream from the muffler.

From the front of your muffler, follow the tubing forward to the catalytic converter, then forward to the engine exhaust manifold.

If you start with the car sitting for a few hours to make sure it's cold, you can use your hand to feel for blowing leaks while the engine is running, but chances are you'll be able to hear it. be careful of the catalytic converter itself, as it heats up fast, so check that first.

Once you've found the leak, the fix depends on the emissions laws in your state. If you have none, and the leak is in the middle of the pipe, you can buy pipe patchers (metal preferred) through auto parts stores or catalogs/websites. If you have strict emissions laws, or the leak is at the junction of the catalytic converter and pipe, you'll need to replace the failing part.

Exhaust pipe rattles when car idles. Had muffler


Check the heat shield on the Catalytic Converter, after a few years they start to rust off and rattle. Crawl under the Pathfinder and bang along the Converter and muffler area and see where it's coming from.   Good chances are, it's from the heat shield since you already had everything changed from the Cat back.
Good luck and hope this helps.

We took our pick-up to the local Ford Dealership to find out why it was running so rough,especially when it was sitting still. It took 3-trips to the Ford House in one week before they could tell me...


The Ford guys you are going to are absolute morons. The engine light likely indicates misfire(s) codes. maybe catalyst inefficiency, but that would be due to the misfiring. Take it to a decent shop that has been in your area for a long time, tell them to tune it up and diagnose it properly. Ford trucks have a very common problem with bad coil packs and coil pack extensions. I can almost promise you this is your problem. Mention coil packs to the mechanic just to twig his memory and he can check his scanner for which ones are suspect.

Sounds like there might be something inside of your exhaust creating pressure making your pipes hot. You might need a new Catalytic Converter. Dont wait too long to check this out, because if you do need a new Catalytic converter, your exhaust Manifold MAY Melt to your Head because of the heat.

Muffler part


You need to read your warranty for specific exclusions! That is the only way to find out what is covered in your warranty. Even if they replaced the resonator in 05, it may be excluded in your warranty.

If they did not replace, then you will have to pay for the replacement.

Good Luck
