A few months back I started having issues with starting when the engine is warm. If the engine is cold it starts right up even after a month but if it's warm it starts up then immediately stalls after the starter shuts off (this happens like 4 times out of 5), it takes 2-3 tries to get it started (giving it a little gas also works). It also idles a bit rough after the engine has warmed up, it sounds like it's skipping revs. Does anyone know why this could be?
