Having problem starting the car, I would turn the key the engine would try to start after trying several times the engine would eventually start even when warm same problem. It was using a more fuel than usual. I replaced MAF sensor new one, new air filter. Now it started first time and ran well, I thought the problem was fixed. The problem now seems to be returning, not as bad as before, but still need to try several times before starting. I replaced the plugs and cleaned the injectors.

I am experiencing on my car, when I start the car it stays on but vibrates and suddenly goes off after few seconds. I have clean up the throttle body, MAF sensor plus oxygen sensor
but still have the same problem. Any one here having the same issues please help me out.
