CarComplaints.com Notes: Except for a minor issue with cracked motor mounts, the 2007 MAZDA3 is a fantastic vehicle with a great reputation.
If you need to replace the motor mounts, first ask your dealer if they'll cover it -- the motor mounts were dealt with in a TSB & were recalled for some model years. Otherwise buy aftermarket motor mounts -- owners report this solves the problem. If you use the same OEM parts, they may just crack again.
Changed the MAF, cleaned out the throttle body and injectors as well as clear the computer and reset everything. The problem comes up ever 1.5 months. usually fixed by resetting the computer. The annoying part is the jumping idle in neutral happens very sporadically and hard to figure out what could be causing it as there is no check engine light
