This car is stock - 80k miles, never had any fuel other than brand name ( exxon ) 89 octane. When trying to pull away from a light after it has run normally for at least the last few mins during warmup, it will hesitate and almost die.. Within 5 secs it usually recovers and then drives normally. The problem has happened maybe 8 times in the last 6 months. No codes and its always had routine maintenance. About to try a bottle of injector cleaner.

Any other suggestions on what to look for?
