1994 SC400: Slow starter and "jumpy" between 40-50 mph

This 1994 SC400 starts on the second try, or after a sustained crank of 2-3 seconds. Starts right up after the warm-up though. There's also a "jumpy" gas pedal between 40-50 mph, as if not enough fuel, or out of time. Then again, I've read about this SC problem in the Club Lexus forum. I have the OBD1 diagnostics so the engine checks haven't been helpful for troubleshooting. The car still looks great; any ideas, sell, trade, enjoy as-is? Thanks.
