When i start it up i have to let it run for a while or it doesn't have much power and the engine light blinks. In order for it to drive normally i have to turn the car off and when i start it backup it runs ok . Also it makes a whinning sound while im driveing and a small backfireing noise under the front left side of the car.And durring acceleration (like when im passing or just wanting to get on it) it does a pause and never accelerates at all, no power.It still run good over all. Also engine electronics light is on when i crank the car. Thanks for the help.
