^ Exactly, if you are mechanically inclined it may be a good idea to tear into it a little and start replacing the vacuum lines on the car. possibly even a tune up too. probably be less than 175 for a full tune up and vacuum lines. just remember have good diagrams or take pictures if you feel unsure!

The 03 codes also include o2 sensor if im not mistaken. Most likely a bad o2 sensor...

My 2009 Miata has gremlins. I will be driving along and the lights on the dash begin blinking and the radio will not turn up down off or change channels. I took it to the local dealer who said they can't do anything unless I bring it to them while it's happening. This is a random thing. It lasts for a few minutes and then everything is fine. It might only happen once every few months. I can't "make" it happen. Any ideas? 2 Answers
