Question about 2001 Nissan Maxima

1 Answer

Resonator pipe I have a 2001 maxima that rattles continuously. i was finally told after 2 years of taking the car to many repair shops it was the resonator pipe. My questions:1. How much should I expect to pay for parts and labor? 2. Am I putting my safety at risk--driving more than 60 miles per day? The mileage: 166,000

No, the resonator pipe simly rattles because the pipe has something loose or broken off on the inside of it normally, it will have very minimal effects on performance and driveability if any at all actually. Just have a shop unbolt it, or cut it off on some designs, and then either empty it out, repair it, or just replace the part or section of exhaust that was cut out. It's a fairly cheap fix and even better if you have a friend do it that has ever had a lil experience with exhaust pipe work. good luck buddy, hope that helps ya out!! cheers!!

DIY Replace Back Muffler / Resonator with Straight PipeSubject: DIY Replace Back...


DIY Replace Back Muffler / Resonator with Straight PipeSubject: DIY Replace Back Muffler / Resonator with Straight Pipe
Title: Increase Fuel MPG by Replacing Back Muffler

Overview:
When your back muffler fails, and or if you want a bit more gas milage, replacing the back muffler with a straight pipe seems to work fine and increase MPG. This is much cheaper than purchasing a back muffler with DIY or to have a local customer shop install a straight pipe.

Symptoms:
Back muffler failing, onion peeling and / or holes in the back muffler.

Experience Level:
Medium

Tools Needed:
Hack Saw, Ratchets, Wrenches, etc.

Time Needed:
About 1 hour:

Parts Needed:
Pipe parts from local auto store. Exhaust sealers, hangers, pipe tip (stainless)

Procedure:
Remove the back muffler by cutting the pipe before the muffler about 2 inches in front of the muffler. Replace with straight pipe components or have a shop do it. You will need some time to get it 100% right. It took me a couple of tries.

Outcome:
- Money savings in replacement.
- Slightly louder, but not much. Actually a better sound (subjective)
- 1-5 MPG gas savings, especially on open road.

Discussion:
I have done this on a 99 9-5 I4 for about 1 year now and it seems to be working fine. I am getting about 3+ MPG on the open road since this was done. It is an automatic with 140k miles solid 29-30 MPG with regular fuel on the open road. I really do not see the need for the back muffler / resonator at the present time.

I will be doing this on a 2001 V6 wagon soon. The muffler will be failing soon.

I just noticed a rattle when I shut off car...could it be a loose exhaust?


Might be Exhaust, but if Exhaust is loose , you usualy here a rattle when you are also driving the car on the road. Best to take Car to local Repairer , put Car on ramp , and take a look , as it could be something else that Rattles.

Iddle and Throttle problem!


had the same problem with the same year model, changed the idle position sensor, did not fix problem. took it to dealer because I was told that it had to have an idle relearn program ran on it, it didn't take and the dealer toldme that I need a ECM (engine control module) basically a new computer and it would cost with labor about 1100.00 dollars.

I have a Nissan Maxima 2004 3.5 SE. It makes a rattling sound from the engine when I start the it or when the engine is running but idle. I have been told this is the timing chain that needs to be...


The rattle that you hear is the upper timing chain tensioners, they can be changed without doing the entire timing chain job, which is really expensive and difficult.

Cant find o2 sensor looking for upstream bank 1 any one want to help?


It should be located near the outlet in the rear exhaust manifold, ahead of the converter. The downstream sensor 2 is the one located behind the converter or sometimes in the rear of the converter body.

The indicator sevice your engine soon light up. See the repair guy and said it's the catalytic converter in the front and middle plus 2 oxygen sensor. Please advice


If a converter is bad, its usually clogged or the ceramic insides is chipping away
resulting in a rattling noise. Kinda like a baby rattle. The car will emit a rotton eggs smell or sulfur odor if the converter is bad. Clogged converter will result in the car stalling soon after its started.
Does your do this ?
My first repair would be the O2 sensors. they just screw into the exhaust pipes...near the converter
Usually, new O2 sensors will solve poor performance and gas mileage.
Some cars have more than one. These are about $30-40 dollars each.
Converters are part of the exhaust pipes that are sometimes shaped in a "H" configuration...so the whole exhaust pipe will need to be replaced that has the converters on it. Its a one piece
assembly and cost a bit more than the O2 sensors. Change or repair one variable at a time to attack the problem and be more cost effective.
Hope this lead you in the right direction !

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.

Rattleing noise between 2500-3500 rpms 01 protege


Have you checked the catalytic converter (also reffered to as simply a Cat by mecanics)? It's the first big canister you encounter on the exhaust line right after the manifold and before the resonator and/or muffler. After a while rust and time can cause either the casing itself to come loose and rattle, or the insides themselves break up and rattle around the cat. And being where it is it often resonates sound around the engine compartment, making it seem the sound is coming from elsewhere than it actually is. And while your at it don't forget to check the flex pipe usually connected to the cat also (some models do not have a flex pipe though). If all that is fine, then the other things to check would be the accessory brackets, wire holders and the like. With vibration and time, sometimes they loosen up and start to rattle. Still nothing? check the suspension parts for anything loose (IE. sway bar links, coils springs, tie-rod, suspension tables). Other than that there isn't much in there that can rattle. If you look at how an engine is built, you'll see that there isn't much inside that can rattle around without causing the engine to fail altogether. I'm not saying it can't happen though, but it's highly improbable. Hope this helps
