Toyota - Sienna :: 1999 - Loud Exhaust Noise / Bad Catalytic Convertor?
Oct 19, 2014
Okay, my wife has a '99 Toyota Sienna with over 200 k miles. Recently, it has began making a loud exhaust noise. I looked at the exhaust system and cannot see any obvious holes. Also, her check engine light has been on for a while. I checked it and it said misfire in cylinder 5 (can't remember the code). Changed plugs and all, still the light. It also idles very high. There's no rotten egg smell that I can tell, but she does say that it seems like it doesn't have a lot of power when accelerating.

i just bought a cherry bomb glass pack and an exhaust system from summit. I am considering running no catalytic convertor. Anything i should know? I know it wont pass inspection but my truck wont pass right now anyway. I am more concerned with loss of power, or worse gas millage....

The engine light on my 2001 Toyota Solara V6 keeps coming on with a code that indicates the Catalytic convertor. The convertor has been replaced 3 times with Mineke non-OEM replacements. The O2 sensor on the muffler has also been replaced.
Question, is there any other repair that can be done to correct this short of Toyota doing a full exhaust replacement?

After hearing some loud noise coming from my exhaust system, it was determined that there is a hole (from rust) in part of the cat. assembly. Three shops advised for replacement, there are no aftermarket products for this unit. I have NOT gotten any error codes, the only problem is the noise. What to do? The car is 10 years old with 86000 miles. I have been reading about some of you getting just the one piece and having it welded on, but I do not believe any of the shops here will do that, and indicated that it would be a very temporary fix.

Chk engine light is on. Checked it at Advance Auto and indicated either cat or the O2 sensor (rear). So, I went to replace the O2 sensor and learned the hard way that you can't just unscrew the nut. I torqued off the stud to which the O2 sensor attaches. Muffler shop told me you need to heat up the stud/nut first to remove it. Oh well, lesson learned. So, I'm looking at replacing the pipe with the catalytic converter attached since I can't seem to fix the broken stud (or actually get the one I didn't break off). The problem is, my car is apparently a CA model and has the special cat on it. I live in VA. What sort of problems might I run into if I replaced the cat with a non-CA version? They are significantly less expensive. This is for a 2003 Toyota Siienna

I own a 2004 Ford Escape, auto, v6. I bought the car in 2007 and have had trouble with my check engine light ever since. It is usually on, but will turn off shortly after I wash it (then back on a week or so later). When mechanics test for the code, they say that my catalytic convertor needs to be replaced. In addition to the on/off strange behavior, I have been driving this car for 4 years now with no major mechanical trouble that I can only assume would result from not replacing the CC. This would be very expensive repair, one I am not interested in doing if this is possibly just an electrical problem. I am ready to get this problem solved and start driving check engine light free.

I own a 1999 Toyota sienna that has 112,000 miles. For the past few months there has been a whirring noise that seems to be coming from the center engine compartment. It started quietly and now has increased in volume. It reminds me of a speedometer cable that is beginning to fail. I have taken it to my trusted mechanic for a diagnosis and he thought it was metal on metal noise from the transmission. I have owned cars for 40 plus years and have'nt heard of this type of tranny noise. What could be causing this? It makes this noise under power and when I release the accelerator the noise almost disappears. Also there is a clunking noise coming from the passenger front wheel after releasing the brake pedal when I come to a stop. I have replaced the strut,ball joint,and lower control arm bushing trying to remedy this. I cannot find anything else that is loose.

Yesterday my 1995 Toyota Corolla (which runs well otherwise) started making the loudest rumbling exhaust sound I've ever heard whenever I stepped on the gas pedal. It also felt like it had trouble accelerating when I would try to get going after a stop. I took it to a mechanic right away, who says it needs a new catalytic converter and resonator pipe.
My boyfriend says this is a repair he could do. He has done some car repair and worked with a mechanic before, so I am considering trusting him on that, but I don't know what types of repairs he's done before and I know he has never worked on this model. What would you take into consideration whether or not it would be safe to attempt this repair at home?

Lately my Sienna makes this noise whenever it is started. The noise lasts for 5-10 seconds. It builds up very loud towards the end and then stops abruptly. I made a recording of the sound and have attached it.

Long story, I'll try to make this short, 2000 E250 5.4L What would or could happen if the catalytic converter was removed from the exhaust system?

My truck just started running really loud when it's cold and the leak goes away when it warms up to operating temperature.I did a little bit of investigating and I have found where the leak is coming from at the end of the exhaust manifold where the donut gasket meets the catalytic converters. It appears that the bolts rotted that hold the system together at the gasket. What should I do to repair this? I don't really want to replace the whole manifold because I know I'll break a stud off in the engine because everything is pretty rusty down there. I even took some pictures of the problem....

I own a 2005 Sienna CE with about 100,100 miles. In the past couple of weeks, I noticed that when I go into reverse, the car makes a whistling noise. At first I thought it was when I press on the brakes but it appears to make the noise even when not braking. It does not do this all the time; only sometimes. It appears to do it more when reversing and going down a slope.
I tried googling this but couldn't find anything. Some people say the brakes which were all replaced a couple of months ago.
Not sure if it is related but the car also makes low chirping noise when driving about 40 miles per hour.

I have a 2006 Toyota Sienna with approx 64K miles. Recently, I am hearing a squealing noise when the AC clutch engages (AC is working fine and blows very cold air). When AC is off for when the clutch is not engaged - no noise at all..... I have been getting alot of different answers as to what it could be and it is very confusing.... to me - it sounds like a clutch issue and I have seen videos on how to take apart and see if it is a bearing or bad clutch. I did pull the belt and checked the pulley - it turns freely and there is no bearing movement. How I can go about getting it repaired without replacing the entire compressor and other expensive parts.

My 2000 Toyota Sienna has been making some concerning noises. It makes a periodic grinding noise, the period is related to the wheel speed...i.e. the noise happens once each time the wheel goes around. I can hear it while I drive, and it's even louder when I roll down the windows. The weird thing is that the noise stops when I hit either the breaks or the gas. First mechanic says that the wheel bearings are shot, and the second says they're fine. There is no "jet engine taking off" noise that I am told is typical of shot bearings, but there is a wump-wump-wump noise at higher speeds.

Having been on a long road trip, I noticed that every time I switch off the engine, there is a grinding noise coming from the engine. Took the van in to Toyota for a regular service, they could not find anything wrong. I then took it to an alignment place having replaced all four tires. They heard the noise straight away and think it is a worn bearing in the cooling fan in the alternator. 2007 Toyota Sienna LE FWD... The car only has 22,956 miles on it.

Had my wheel bearings replaced 3 weeks ago from a mechanic I never went to, as mine was on vacation. 3 days later tire fell off while driving. So we took it to my regular mechanic and had all safety issues fixed. New brakes, rotor, hub. But noticed that a grinding noise appeared. Took it back to mechanic, and he said that it was due to the spindle being slightly bent. Thst it wasnt a safety concerns, but will cause rotor/ brakes to wear out quicker.
I'd like to trust my mechanic, as he has always done good work for me in the past. But am a little shaky over every noise. I'd he correct?How soon should I get it repaired? I just dropped over $600 to get the can drivable again. So if I can push it off until I can afford it that would be great! Otherwise, I might need a small loan to repair.

For about a year now, my trusty Sienna has been making this intermittent little squeak. It's not loud (it's not the belt!). It seems to be coming from the passenger side, toward the rear. It only happens when I am moving. It seems to happen when I am running the AC. It is a soft little chirpy-ish squeak, about 2 seconds in duration. It sounds for all the world like a vent opening up with a squeak. Driveability is in no way compromised.

I have a 2002 Toyota Sienna van. My garage failed to check the brake shoes as requested, so I gouged the back brake drums and had to have them replaced. Shortly afterwards, whenever I brake, in the last 2-3 seconds before I stop there is a thumping noise from the right rear wheel. It will thump a few times, maybe 2-5 times, perhaps one thump per wheel rotation. I don't feel any pulsing in the brake pedal, and except for the noise braking seems normal. Could this be due to the shoe adjustment being too loose, so the shoe has room to pulse inside the drum?

I have a 98 Toyota sienna and it has started making a thud noise and skipping a bit when accelerating or going up even a slight incline. I have been told everything from it needs new plugs/wires to a new transmission. Could these cause similar problems?

Within the last few weeks my Sienna has begun making a terrible noise and shudder when I accelerate. It seems like it is worse on the front passenger side. When slowly accelerating from a stop it makes a hollow pitched metal scraping sound that increases frequency with speed (up to 25-30mph) and at higher speeds just the shudder, no sound. Initially this was intermittent but now it is an all the time thing.
The sound and shudder only happens when accelerating, regardless of speed. When you are at cruising speed on the highway there's no shudder as long as you are at constant speed and at any time if you take your foot off of the gas pedal the noise and shudder stop. Because of the link to acceleration I don't think its a wheel bearing.

I have a 99 Toyota Sienna with an automatic sliding door that has failed. Cost to repair is high $$$. Would like to disable the motor and automatic mechanism and make it a regular manual sliding. Can it be done? If so need a repair shop?
