2009 Sienna stalls immediately after starting. Will start after a couple of tries by giving it all to the accelerator. Runs fine once started. Independent mechanic said throttle body. He cleaned it. Ran Seafoam through. No change. New throttle body. No change. New mass airflow sensor. No change. New spark plugs. No change. I have reset the idle according to several YouTube videos. I have also disconnected the battery for 1 hour and 48 hours attempting to reset the computer (which is advised after the those new parts are installed). His guessing has cost me $670 and the car still doesn’t start without failing once, twice, or more. This is my teenage daughter’s vehicle and I don’t want her to become stranded to and from work, so the van is parked and she’s driving my car. HELP!!!
