Is vapor lock even a possibility with fuel injection and the high fuel pressure created by the electric fuel pump? Seems like, unless the pump was going bad, this is a non-issue. Even in the pre-fuel injection days, vapor lock usually happened after the engine was shut off and it was then that the fuel would percolate in the fuel lines. When you energize the ignition just before starting the engine, the fuel pump pressurizes the system, and that should take care of any possible vapor lock problems - IF the pump is working correctly. At any rate, I know when I turn on my AC, it seems like the engine is surging because, well, it is due to the extra load everytime the AC clutch engages.
