2009 Toyota Corolla that I received from a local shop who just installed new coils, plugs, injectors, AND a PCM. I walk you through the process that I used to diagnose the true cause of the misfire!
I should have explained one thing a little better though! I dont do leak downs at TRUE BDC! I do leak downs right after the intake valve closes. So as close to bottom as possible after the intake valve closes. Then make sure that you're aware that the air will cause the piston to be forced down so you need to hold the engine from rotating!
