Update:
dad went to get the car and he said he pushed it a bit, and the same **** happened again. The car is at the dealer again and they say if the cant solve the problem they are gonna look into getting me a new motor cause they said they have done all the required checks...

 

At least ur lucky mazda didn't charge u anything and they're going to fix ur rx8.... the mazda dealer near my place is charging me for whatever they wanna look into

 

I honestly don't know if you should get it or not. That's the truth.

Whoever(and don't tell us) wrote you that note seemed to know what the hell he was talking about, so....................

Only suggestion I can offer is....................IF money wasn't and issue, then for $119.00 I might and if I found I didn't need it, I could either sell it on here, or more likely..........I would keep as a back up.

 

Here's what i've got:

Brand new OEM 04-10 IGNITION COIL SET,

i've ordered these, what do you think?

 

I think you already have new plugs right? I'm too lazy to go back and look.

 

ya i've already changed the spark plugs and put them in the engine already last week........ im waiting for the orders to arrive by next week.

hey i've also changed the oil last week! lol so next week when I change all the coils, cables and stuff and take it to mazda to have it inspected, they're goino ask me where did u get ur coils from? where did u do the maintenance? lol I hope that doesn't void my warranty on engine and CAT! :S lol the owner before me took the car to mazda only once! for an oil change and that was it..... which means Mazda would prolly tell me ur engine is not covered! :S im abit nervous! Hopefully its not the engine or the cat! :s

 

CAT it won't matter at all.
Engine.......you would probably have to have receipts since you bought the car for oil/filters.
Start keeping them.

 

ya it sucks not knowing what the other owner did to ur car!..... I bought my rx8 around January 2010.... there's a big gap between 2004 to January 2010!
