Hi Scotty, I just swapped the engine on my 2011 Toyota Sienna with an used engine (engine was supposedly compression checked and passed) since the one in there blew. Coolant was running out of the exhaust pipe on my old engine. Now that i swapped the engine I have 2 permanent codes. Codes: P0018, P0019. Other codes Im also getting are P0300, P0302, P0304 (some times), and P0306 (some times). All the code pertains to bank 2. Van runs fine and strong but in idle,  you can feel the car slightly shake a little (not much) with check engine light with those codes. Also, I noticed the LTFT bank 1 is 13% whereas LTFT bank 2 is the opposite at -13%. Any thoughts??? Am I screwed???
