Re: MAZDA 3 ROUGH IDLE FIXED
Had the exact same problem. Idle would dip at stops, a couple of times the rpm went so low it almost stalled, when it would do this the check engine light would come on for a split second. Anyway I took out the EVAP SOLENOID which was super easy to remove, sprayed it out with pb, let it sit, and blew it out. Idle is back to normal =] Thanks for the help "JOECO"
