I have changed the battery 3 times since Thanksgiving & took it in to my local Toyota dealer. The dealer says it's not the battery, starter, spark plugs, alternator and shows no error codes. Twice, I brought it back home and car cannot start the next day. After battery change, I can get the car to start by flooring the gas and holding it for 3 minutes and keep holding. It will make a loud pop noise under the driver's side of the hood. Dealer checked my air intake valve and showed a little carbon dust. This car has about 1/2 tank gas & usually is used for weekend driving only. Please advise as to what to fix.
