Hi I have a 2008 es standard I swapped the motor fro .a 2015 es and when I crank the car over it just goes into wide open. Throttle I have not tension on the gas peddle either should I swap my old throttle body on it or is the car gonna need to be flashed ? Also side note I have an erg port that isn't blocked yet could that cause this issue ? And advice or help would be awesome

Yes, block the EGR port and try again. It has a direct path into your intake manifold. The EGR system works by taking exhaust gases and pushing them into your intake manifold for smog **** reasons. Also make sure the throttle body plate is shut when you start the car. If it's not those two, you have a major vacuum leak somewhere.

Thanks so much for your advice haha I have been looking everywhere for even something pointing me in a direction to start thanks!
