Golf IV R32 :: How To Make Catalytic Converter Ready
Took my car in for emissions and says catalytic converter is not ready.
What can I do to make this go to "ready"?
I've recently got my computer flashed with new programming.
Since it's been flashed, I've driven the car over 400 miles.
All of the cars self checks should be complete, I can't figure out why the catalytic converter won't go to ready!
Any thoughts or tricks to make it work?
Mazda - Miata :: 2000 - Catalytic Converter Keeps Blowing Out

My husband,who is an engineer and has done all of our car maintenance for decades is stumped by our 2000 Mazda MPV. He replaced the catalytic converter and put every thing back together, but the car won't run. Will start, but dies right away. Took off new cat,and runs with that off, but not sure why it won't run with the cat on.

4.6L DOHC - My driver's side catalytic converter is making quite a bit of noise during acceleration when the engine is warm. I have no trouble codes, no cel and the truck seems to be running fine in general.
I am exploring repair possibilities. I've talked to two shops - one general repair, one exhaust specialist. Neither gave me any options other than to replace the whole system. That isn't an option. I'm a semi-competent home mechanic and if that's what has to be done I'll just buy the walker system from RA and do it myself.
Nissan - Maxima :: Replace Catalytic Converter / MAF Sensor
I've been having issues with my car, i took it to Orielly's & they ran diagnostics, one of the codes said a recommended fix was replace the MAF sensor. Today I took it by an auto shop for them to look at, and the guy said it was my catalytic converter, and I mentioned the MAF sensor, he said fixing the CC would take care of the MAF sensor malfunction. So I have a couple questions...
1. Is what he said correct?
2. If you have a bad CC, does it ever NOT smell bad?
Bc I've never smelled anything other than stinky exhaust, never any rotten egg smell.
It's a 98 Nissan Maxima, 6 cyl. it has 265K miles.
Oldsmobile - Alero :: Possible To Disable Catalytic Converter Sensor?
My wife's car has the check engine light on and she was told by her mechanic that it was the catalytic converter going out, to ignore it. I am thinking that I ought to be able to build a jumper for the sensor and fool it into thinking that it is working, reset the check engine light and wait till it starts to fall apart before replacing it. I'm tired of driving with the check engine light on, maybe missing something else that needs attention rather than the cat. it has 140k on this car but is in great condition. I am a diesel mechanic, no real experience with gas vehicles in a long time. oh, and we just got married. Or maybe I just ought to stay late at work and get this thing up on the rack and look into it. Put the scope on it myself??
View 19 RepliesSubaru - Forester :: Intermittently Stuttering / Bad Catalytic Converter Cause O2 Sensor?
2001 sub forrester. In 2009 it was intermittently stuttering: tuneup, new coil, finally O2 sensor (both) replaced which fixed it. In Oct started to do the same thing. First the back then the front sensor replaced but they commented the flow was low on the catalytic converter but wouldn't say it could be the cause of the sensor issue. Now the O2 sensors are on either end of the converter and the car is starting with early signs already. Is is reasonable that it is the catalytic converter? I am wrestling with just having them do the full tuneup and replace the converter or am I crazy?

I wanted to get some input about lowering my 2010 Corolla LE. I wanted to go about 3 inches, but have been told i will need to replace some extra parts. Not sure where to begin, but i'm not afraid to ask questions or get dirty. I hear a lot of different things and i'm on over load with info.
View 7 RepliesJeep - Liberty :: 2006 - CEL Came On Intermittently - Catalytic Converter Or O2 Sensor?
I have a 2006 Jeep Liberty with 135,000 miles. My check engine light is mostly on. Sometimes it is off. One mechanic tested the car and said the catalytic converter is bad. Another mechanic said that test can often be false positive and it might only be the O2 sensor. The difference between the two is about $1,000. Which mechanic is correct? My car is registered in a state that doesn't do car inspections.

I have a 2004 Camry XLE and the CAT does not heat up and be in ready state. After using SCANTOOL on the computer, it does not pick up any reading for O2 Sensor bank 2. I have changed a new o2 sensor at the bottom of the care by the oil pan. Still it does not provide any data. thus it leads me to believe that it's an electrical, fuse, or OBD computer has issue. So I am asking - do the O2 Sensor has fuses/use fuses?
View 9 RepliesMazda - Mazda6 :: Misfiring On Cylinder 3 / CEL Flashing
My '04 v6 wagon 100K will misfire in really damp conditions. Last fall after going through a massive puddle and today after sitting for a couple of days of warm damp foggy & rainy New England spring weather. OBDII scanner is reporting cylinder 3 as the one misfiring in the fall, today there were a ton of codes (that I didn't note).
So I made it about 2 miles from the house and had to turn back. No power, check light flashing. I had to put it in manual and keep the revs highish (3-4K). When I got home the exhaust manifold was glowing yellow, assuming one or more cylinders were passing fuel out to the exhaust and it was being burnt off in the manifold.
My question: could I have damaged any gaskets back there? This could be my imagination but I think I'm hearing a new noise that I'd normally attribute to an exhaust leak downstream of the muffler, very subtle - like a gentle light but rapid thud. I only hear this noise with my ear to in the front driver's wheel well. There's no ticking noise I normally attribute to leaks near the manifold. My imagination or is it easy to damage something in the circumstances I describe?

Mazda - Mazda6 :: 2007 - Loud Sound That Comes From Under The Hood
I have a 2007 Mazda 6 with 133000 miles on it. Recently it has started making a very loud sound that comes from under the hood. The sounds is comparable to the sound a semi truck makes if it is idling. The noise is not constant, usually happens when I put the car in park or if I'm driving at low speed (under 20mph). The sound lasts around one minute.

Mazda6. I have a check engine light for a random misfire on cylinder 2. I have changed the spark plugs, the injector, and even the cylinder 2 coil, but still have that random misfire. The funny thing is that it would run great within short (about 30 miles) one way trips. Lately, I have gotten a new symptom: It has started to hesitate and can feel a loss of power but only once the car has been driven for about ten minutes non stop. Can't figure this out.
View 12 RepliesMazda - Mazda6 :: 2003 - Car Suddenly Stops While Driving
I have a 2003 Mazda 6, 5-speed manual transmission. I was driving on the highway today (going about 65mph), and all of a sudden, my car kind of "jolted" (like it stalled out). When I tried pushing the gas pedal, the car wouldn't accelerate. When this happened, the check engine light (and some other lights) went on, too. I pulled over to the side, turned the car off, and turned it back on. It seemed to start fine and gas/acceleration was working. Fortunately, I was able to get home, but it started doing it more frequently up until I got to my apartment. Each time, I had to turn the car off and restart it.
Oddly enough, when the car does this and I pull over to the side, the engine is still on. However, even though the engine is on and the car is idling, I noticed the RPMs were sort of jumping between 0 and 1000, and the engine was sputtering (like it was sputtering with the RPMs jumping, the only way I can describe this sputtering is like a heart beat). The only thing that seems to work is to turn the car off and turn it back on, which will then allow the gas pedal to work, only to have it happen again a few minutes later. The gas pedal doesn't get stuck or anything, it's just pushing it doesn't seem to accelerate the car.
I've already had the engine replaced on this car last year (at 80K) and the clutch a few months ago, too.
Mazda - Mazda6 :: Front End Vibration At Certain Speed And When Turning Right
2009 mazda6, I feel some vibration feels like wheel is out of balance coming from the front left wheel, it's most noticable at 30mph and again at 60mph. It's more noticable when i'm turning right, e.g. shiting to the right lane.
Already replaced four tires, balanced the tires and replaced front struts and rear shocks.. and it's still there!!
when shifting to the right lane, the vibration feels like da-da-da-da-da.. like I'm driving over some washboard road.
What could this be, is this CV-joint? can I ask dealer to check out CV-joint see if it's ok?
Mazda - Mazda6 :: 2006 - Bad Noise And Jerk In 4th Gear
we have an 2006 Mazada 6 automatic transmission with the option of manually shifting gears. we have had it a year and the only maintenance is work on the air conditioner, oil changes, and new tires. when accelerating on an incline or sometimes during/after a curve as it shifts into 4th gear it makes a terrible noise and the whole car jerks. the best way I know to describe it is it feels as if the bottom of the car is about to fall out! when we first purchased it, it done this a couple times and basically quit doing it for a few months.
It seems to be getting worse though. we have never had a check engine light. we sent a can of "sea foam" through the gas tank and this seemed to work. a local mechanic examined it and test drove it but couldn’t find anything wrong with it. (of course it didn’t act like this when he drove it!) I called mazda dealership and they cant tell us anything without us bringing it in and charging us no telling how much just to look at it. no one seems to be able to figure this out….
Mazda - Mazda6 :: 2003 - Chronic Ignition Coil Cause?
Can a problem elsewhere in the system cause ignition coils to go bad? I have an '03 Mazda 6s, 147k miles, owned it since new (Dec '02). 3 1/2 ~ 4 years ago, over a period of 6 months I had to replace 4 of the 6 coils. A month ago, one of the replaced coils went bad so I had all three rear bank coils replaced (cheaper to do all three at once rather than one at at a time since half the engine needs to be disassembled to get at them). This week, I started to get the initial symptom of a coil going bad on me: Occasional stuttering in the engine.
This issue always starts when it's wet outside. The first few times it started when going through a car wash, this last time was right after Super Storm Sandy dumped a lot of rain (I am not in one of the flooded areas, NH just got a lot of rain).
Mazda - Mazda6 :: 2003 - Some Hesitancy To Shift Into 1st When Cold
I have a 2003 Mazda6, 108K miles. Had the ATF changed last December at the dealer. Prior to this, there was some hesitancy to shift into 1st when cold. Last several months, it has gotten worse. Engine revs (as much as I allow it, which ain't much) and then goes into first. Dealer thought they had overfilled the ATF, and reflushed and refilled. Said they couldn't find any other problems. There is no CEL. Problem was better for a short while after fluid change, but now back to long hesitation. Car goes into Reverse fine when cold. Once the car is warm, I don't notice the hesitancy to shift to first. How to diagnose?
