For a while now my car dies occasionally. Usually when i first start it back up i'll start going then if i stop and start up again it will just die on me, and when I idle the gas when i''m stopped everyting is fine. Sometimes it kind of sounds like the engine is cutting out. I also noticed that my RPMs dont seem to be going as fast when I am stopped. Usually they are close to 1000 but now they look like they are around 500. I'm not sure but i'm thinking the fuel injectors are going out. And I have used fuel infector cleaner a couple tanks ago and I have been using octane booster. Any ideas? Thanks.
