Question

I'm getting multiple engine codes (misfires , misfires on start ups etc.

Answer 1

Recieving multiple misfire at start up. what you have is a mifire with injector shut down, try this, clear the code, at engine start up pull out the oil dipstick, if there is excessive vacuum being drawn into the engine you would need a PCV assembly. a ruptured PCV valve will do exactly what you experience misfire at start up..
