Hello I am Jason and I am new to the forum and new to Mazda. I recently got married and my wife has a 08' Mazda3 Hatchback 2.3L 5 speed. It has recently started having an issue on cold starting the car. Starts fine but when I give it gas it has a spit/sputter until the engine gets warm and then the car doesn't do it again. And it's mainly in lower RPM's. I have already changed the plugs, put fuel injector cleaner in it, cleaned every electrical connection just in case a sensor was throwing a bad signal. I am going to take it to a shop and have them look at it this weekend, but I am looking to see if anyone has any information for me to help point me in the right direction. Thanks in advance for any help you can give me!
