Toyota - Repair - Corolla :: Loudest Rumbling Exhaust Sound / Catalytic Converter Replacement?
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?

When I took my new used car to the mechanic, complaining how there must be an oil leak cause well by now 9 bottles of oil in 7 weeks time have been put in, the mechanic told me the engine is burning the oil too fast. He said something about the piston, but I got all confused. He also said that the only way to fix this is to replace the engine, but he recommended not to cause it would cost more than the car is worth. This is a 2000 Toyota Corolla. Why this is happening and what i should do about it.

Got a rattle from the car, I think it's the catalytic converter heat shield. Looking for any pictures of what it looks like? I don't know if it is a full cover on our Toyota's, or a half cover. I will post a picture of what mine looks like now that it is rattling later today. Hoping it's an easy fix.

Toyota - Sienna :: 2003 - Replacing CA Catalytic Converter
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

My Toyota Tundra 2011, driven enough to haul a horse locally (6000 plus miles) is now unable to go above 30 mph, it was fine last week. Toyota dealer says it is both of the air injection units and switch. Of course it is out of warranty 3 months.

1996 4runner here (187,500miles), with weld in after market cat (on when purchased, with less than 1000 mile on it). started throwing the 420 code beginning of last summer. Replaced both O2 sensors and same results. Was coming on after every 30-40 miles after resetting, replaced wires, plugs, cleaned throttle body started coming on ever 120 miles or so. Now in the middle of winter it has gone 450 miles and still has not come back on?? Does the winter fuel blends in Georgia, or cold more dense air make a difference on cat performance? Still plan to replace it with a direct fit with a warranty but curious if I am overlooking something.

Toyota says the code is P0420 and the Catalytic Converter is rattling under heavy acceleration showing the Catalytic converter is bad and should be replaced. Toyota wants 2,334.00 which seems very high to me. Is it the Catalytic converter? The car is a 2004 Toyota Prius.

I had my local garage do their electronic check when my check engine light came on. They said the code they got indicated a failed catalytic converter and quoted me $720.00 for a California compliant replacement, including labor. I live in Connecticut. I'd like to take a few days to get a second opinion and second quote, but the garage manager said that driving it in this condition would risk fouling the oxygen sensor, which I recently replaced for a couple hundred bucks.
Should I be concerned about fouling the oxygen sensor by continuing to drive the car? 2000 Toyota Camry...
I looked under the car and the rear attachment bolts to the converter are rusted beyond recognition. I'm tempted to try replacing it myself but it may be a bit beyond my skills.
Toyota - Prius :: Check Engine Light Has Been Coming On - Catalytic Converter Need Replacement
My wife's car is a 2002 Prius, 149 k miles. Lately the check engine light has been coming on. I took it to the dealership, and their assessment is that the catalytic converter needs to be replaced. They are recommending about $2,000 + of repairs. While I am contemplating the practicality of investing that much in keeping this car going I'm wondering if it harmful or dangerous to continue operating this vehicle.
View 12 RepliesToyota - Corolla :: 2003 - Check Engine Code P0420 - Change The Converter
I have a 2003 Toyota Corolla, mileage app. 106,000. Check engine light first came on when driving to destination 40+ miles away (most of my driving is shorter, around-town trips). My mechanic said code is P0420 and so they reset it and said if it comes on again that I need a new cat converter. It did not come on until about 6 weeks later when I was on a longer trip again (had driven about 40-50 miles). Can you tell me if the P0420 code absolutely means that a new cat. conv. is needed or if it could possibly be a sensor or something else hopefully less costly than a new cc?

I recently had my catalytic converter replaced with a non-OEM cat. The check engine light came on and a different shop (different from the shop that replaced the cat) said that it will keep coming on because I had the cat replaced with a non-OEM cat.
View 3 RepliesGolf IV / Jetta IV :: CEL Came On, Car Needs A New Catalytic Converter
I have a 2001 VT GTI with 155K miles on it. It is in very good condition. I have loved the car except for the high maintenance costs that typically seem to be associated with VWs.
I found out this week after my check engine light came on that the car needs a new catalytic converter and a new new secondary air pump.
Let's assume that this diagnosis is correct and the repair is accurate for the sake of this posting (and I have no doubt it is). In other words, I don't want to get my question derailed on that issue.
The car has new Michelin tires on it and runs well. The problem is that it will fail the state emissions test I am required to take next December, and I will either be forced to have the car repaired or will not be able to get updated license tabs (isn't that sweet?!).
It seems that I have a few options:
1. Get the repair done (ouch) and keep driving the car for a few more years. Repair cost is about what the market value of the car is (from what I have seen).
2. Sell the car "as-is" between now and December and see what cash I can get out of it. Any buyer will discount the value of the vehicle based on the repairs needed. Of course, then I'll need a replacement vehicle of some sort.

Town Car :: 4.6 Engine Catalytic Converter Location?
I have a 2000 Lincoln Town Car with a single exhaust system, part of/attached to the frontal area of the exhaust "Y" pipe are two lumps with heat shields, the muffler is obvious in the mid-section of the car, but are those "lumps" the catalytic converters, and if so, why two when the older cars had only one?

Passat (B5) :: Noise And Water From Catalytic Converter
So this morning (Kind of Cold) I went out site and started my car. I heard some noise under the car and I noticed that the noise bad been coming from the Catalytic Converter area and there was water dripping off of it.
My guess is that it was just warming up and the water was from the cold. Is it normal?

Acura - Rsx :: 2004 - Catalytic Converter Malfunction
I own a 2004 Acura RSX that I purchased new nearly 10 years ago. The car currently has 182,000 miles on it. Two years ago (approx. 130,000 miles), I had to replace the catalytic converter and both O2 sensors. This lightened my wallet to the tune of $1,200 (aftermarket franchise, OEM replacement). A few weeks ago, the "check engine" light came on. I used my scanner, and got the dreaded P0420 code, and had it verified by another shop. O2 sensors were OK. What REALLY shocked me was that replacement catalytic converters are only warranted for 5 years/25,000 miles (50k in CA). The first replacement piece lasted 52,000 miles (less than half the miles/years of the original part)
Here are THE QUESTIONS: What killed this catalytic converter? What can I do to prolong the life of this part? My car has the base powertrain that (according to the owner's manual) recommends 87 octane fuel. That's all I've ever used. The mechanic suggested moving up to mid-grade fuel, though he admitted that he wasn't sure.

I have a 2000 Chevy Camaro. Two years ago my catalytic converter went out and I had it replaced. 20,000 miles later my mechanic says that I need to replace it again. Is this accurate? I thought the life of a Catalytic Converter was much longer.
