I had sputtering problems when my CX7 reached about 70k miles (I now have 92k miles). I have started using a fuel injection cleaner that I add to my gas every 5,000 miles. I also do not let it run below a 1/4 tank of gas any more (I find the sputtering is worse when it is below 1/4 tank).
 
In regards to the engine light, for me, it has been the gas cap. A friend of mine who also has a Mazda with high mileage (not CX7) has also had the same problem. I just make sure to push in the gas cap and turn it so it clicks 4 - 5 times. The light rarely comes on any more, and when it does, adjusting the cap fixes the problem.

Heres my full story..My 2007 mazda cx7 will crank and run for about a second and then die...cannot tell if any warning lights are on due to the fact it wont stay on long enough. It first started while i was driving it.. I goosed it down a strait a way and it died..so I attemted to restart and it would start for a second to only to die again. It drove pretty good up until that moment, However I have spent 2 grand on a new timing chain and accutator about 3 months ago.. I am really regreting getting this car last year after seeing all the head aches people are having with the 07 models. And to add insult to injury I just bought brand new tires and had the oil changed and air filter changed. The car just didn't appreciate it if anyone has any suggestions please help..I really appreciate it!

I have not been able to solve my problem yet and am not willing to let the mechanics start putting new parts in it, if they don't know for sure. My starting problems only happens after I fill the tank with gas. I tried it with and without the engine running while filling but every time when I try to start it after filling the tank, it acts like it has ran out of gas. The only way to get it to start is by pushing on the gas pedal for about 10 seconds during that time it coughs and sputters. Then it runs just fine until I fill up the tank again.

Well got great news!! A mechanic friend of ours came and looked at our 07 cx7 and it took him 10 minutes to fix the problem. Come to find out..when I had the oil changed they also changed the air filter, the old one had lots of bugs in it.. well what happened was when ran the car fast that day..it blowed a leftover moth into the air flow sensor and blocked the prongs..and therefore was not getting connection..so all he done was blowed out the moth now our car runs and it runs perfect!!! I know if we had of taken it to the dealer they would have charged alot! so greatful to our friend who was so knowledgeable. If anyone is having starting issues you and needs to check your air flow sensor to see if it is bad he said to just unplug it and if the car runs even if it runs rough just as long as it runs..thats the problem.. fortunately we didn't have to buy any parts! I hope this helps.

If the battery is new and you can't even get the car to crank over-- the connections on the battery must be loose or coroded. Check the connections-retighten-and try again.
