Catalytic Converter wrecked my coils/plugs!!!
 

Anyone have any experience with the catalytic converter wrecking your ignition coils and plugs?? Happened TWICE in 7 months!!! I am quite PISSED off and thinking about a class-action suit..

2004 with 53K miles; insane this should not happen, am I wrong?
Thoughts?

whoa whoa, slow down there Turbo...

Your cat most likely did not ruin your coils. Actually, the opposite is more likely to happen.
You might want to read around a little more, our oem coils are notorious for not lasting very long. I myself have changed out my coils 3 times in the last 3 years. We've had people here report coil failures in as little as 6,000 miles (on an 09 RX-8)

sorry to hear you're having issues but a class action lawsuit will get you nowhere.

How do you know your coils are bad? did you test them?
have you replaced the wires?
how old are your spark plugs?

I don't understand how a bad Cat can cause a problem with coils.

The only people to win in a Class Action Suit are the lawyers.

lolwut??

As Jedi said your coils can cause your cat to fail. Not the other way around.

Who said your catalytic converter caused your Ignition Coils to go bad? I wouldn't mind knowing.

he's filing a class action lolsuit

Your "class" will consist of one plaintiff.

i hope his lawyer passed the bahahar

Is like how your exhaust would damage your intake.

My wiper fluid caused my tires to wear out!

I use my wiper fluid from time to time and then I noticed my tire tread was starting to wear down... I demand 1,000,000,000 dollars!

Every time I turn the engine on my fuel gauge goes down, wtf

failthread

did a dealership tell you that? Cause you might want to go asking them for some refunds. I think it's odd how you think you have a valid claim to start a class action lawsuit 5 years after the release of the car that no one has thought of yet. In fact, it's odd to think of making a class action before knowing that at least one other person has experienced the issue.

my shift knob caused me to get a speeding ticket. i demand reparations!

You live in America and you're surprised that someone's first reaction is "OMG I SUE U" when a problem arises? :p:

you are so anti-american!

im going to sue you for not having enough patriotism! you commie bastard!

It's to make it sound more threatening and stuff :p:

"Don't trust the French!" :lol:

i know! thats why you are so anti-american! you hate us!

Catalytic Converter wrecked my coils/plugs!!!
 

I loved all of the replies!! I knew I'd get a response, here's the long story.

Last October, I'm driving home all of a sudden I lost 50% power, and I drove for about 1 mile, stopped, saw smoke coming out of engine, shut off car.

Towed to mechanic; he replaces 2 ignition coils, all 4 plugs since 2 were were replaced from a prior recall and 2 were original. Mileage about 50K. Big $$.

One month ago, car had no symptoms, running fine. Check engine light came on, took to mechanic, said computer tripped 3 codes, cleared codes. Took to dealer because one of the codes related to catalytic converter.

Prior to all of this happening, I kept hearing an intermittent rattle while driving; couldn't pinpoint location or cause.

Two weeks ago, coming home from son's Master's Graduate concert, driving on the 405 in So Ca, check engine light comes on intermittently and also lost 50% power, drove car for about 5 miles until we got to other son's place and had AAA tow to mechanic.

Mechanic now says Catalytic converter culprit, needs replacing, covered under 7/70 warranty. Had car towed to dealer, catalytic converter replaced. Dealer said car still running rough; have car towed back to mechanic. See dealer repair sheet, no cost is present - zero dollars to me. Mechanic said Mazda hiding true cost of repair, probably $1500+. Mechanic thinks Mazda hiding something, I agree, from blog posts we find when I pick up car. He reduces cost of repair since he knows I'm pissed.

He replaced the other 2 ignition coils and all 4 plugs.

Now y'all are saying the ignition coils CAUSED the catalytic converter to fail?? I have never heard of that before, but I don't discount it.

I have spent over $1000.00 repairing my RX8 since last October.

Please elaborate on why some of y'all think the ignition coils could possibly torch the catalytic converter, I need to know details.

Thanks everyone for your posts, they were great and made my day!!!

think about it for a sec
coils/plugs = ignition
cat = after ignition
only flows one way

you make it sound like cats commonly cause coil/plug failure

common thought would be
ignition troubes = run rich = bad for cat

your cat FAILED which is NOT unheard of for this car.. simple as that.

yes a new catalytic converter from Mazda is $1500 but it's covered under the federal emissions warranty.

your car was coincidentally due for coils/plugs.. and you ended up paying big $ for something that easily costs less then $200 if you were to do it yourself.
