Should I expect to shell out a lot of $$ to have it replaced?

thanks in advance

 

No...about an hour.....

 

So they wanna charge me $520 to replace the mounts, is that what I should expect??

 

Are you out of warranty?

I've been trying to get mine replaced under warranty for about a month. First they "could not duplicate" the rough idle and hesitation per TSB. Next time in they had a printout from a Mazda service tech extranet about aftermarket intakes (especially with oiled filters) can cause rough idle and can damage MAFs. They said to put stock intake back on and take it from there. I've cleaned my maf, inspected and found it clean since then, and the idle has gotten worse since having the aftermarket intake.

Good Luck.

 

If you're still within your factory powertrain warranty 6/60K then they are covered under warranty and it should be free.

The specifics on the powertrain warranty can be found here and the explicitly call out engine mounts.

I would swap the intake and bring it back. It's not hard to do and if it still does it then you know you're right and you get it fixed.

 

Wow... they told me powertrain doesn't cover the motor mounts. I wish I would have seen this before.
Thanks
