So back in November the check engine light came on, on the wife's 8.
She said the motor seemed to be running rough at idle, but otherwise normally.
So we take it to the dealer, who check the code - which comes up "misfire".
They say that it wasn't misfiring now, clear the code and charge me $100 !
The weather warmed up and the light stayed out, but as a precaution I bought new plugs, wires and coils and planned to install them when I had some time off, on a nice day ... today !

So .. removing the front wheel to get access to the plugs and what do I see .. the leading rear sparkplug boot was off, and by the corrosion on the plug, had been off for quite awhile !!!



How's that for quality service at the dealer ...
You'd think they would have at least checked ...

I'll bet she's going to run a lot better when I'm done .. ha ha !!
I just wish it hadn't been 3 months since I was at the loser dealership - though I'm still going to let them have it !

 

same happend to me they didnt charge me anything they said it was the starter i just got the car back today , they said the started casued a misfire and carbon build up in the rear rotor , just got it back this morning runs smoother than anything ,,


might be the same issue

 

DON'T BLAME THE DEALER !

This could have happened after they checked the car.

 

All back together .. runs like a dream.

I doubt it ... it's probably been that way since they replaced the plugs for the recall in Oct/06 !

 

bought my rx8 yesterday and it died today.. had to get it towed to the mazda dealership they are replacing the coils and everything tomorrow.. anything else i should be worried about? my car was misfiring idling under 1000rpm and stalled a couple times in idle.
