I don't know if this applies to the 2005 2.2L Malibu but my 2004 Malibu with the same engine had a similar problem. I took it to a chevy dealer and they reprogrammed the engine control module. There seems to have been a problem there known to GM. Since then no more start problems. So as a last resort you could try a good dealer you can trust.
