misfire...after coils and plugs changed.
A couple things:
- Did they give you the RPM at which the test was run?
- If they did it with a piston compression checker they wouldn't have been able to give you 3 separate numbers...

Maybe you should do a compression test yourself. I know it's not as accurate as the "special" tester mazda uses, but it's worth a try.

They said 200 rpm, and IDK what they did really the more I talk to them the more I think they didnt even do one.
nmarz thanks I wanna do that where do I purchase that compression valve? checker/autozone I assume.

Yeah you should be able to pick one up from autozone, not sure of the quality though. For a "decent" quality one at a fair price you could also pick up a Craftsman one from Sears.
I'm going to get a gauge and do the test myself just to know it's done right. If I still get the same numbers, I'm going to court, tired of the runaround.
You can get one from Sears or most auto parts places... You just need to make a little modification to the standard piston ones...
Im almost positive they didn't do the test right. cause my compression numbers they gave me are like 6.4, 6.3, 6.5. From everyone I have talked to who has low compression their cars either won't start and if they do start they don't run well at all, loss of power and such. My car feels no different at all, she starts, runs, idles well everything seems great, cel has been gone for 2 weeks. I was reading on how to check rotory compression you need a specialized tester, when I asked the dealer how they did it, they said same as a piston engine!
Yeah I believe the limit in small claims is 3 grand.
Dennis is the tech's name, Bountiful Mazda is the dealer 801-397-2277.

Thats why I said it sounds fishy, 200 rpm ? lol wow, they SURE have NO IDEA how to do the compression test right. 200 rpm is possible. but they really have no clue what they're tlaking about. Lemme find u the service manual part ... hold on
College helps maybe, but Do they even need college to understand that graph ?
dealership these days .... are really .... something.
