When I start car after a wait of more than 5 hours, the engine will not rev. Past Idle for about 5 minutes -- usually. Simetimes even after all night it will go to accelerate right away. There might be a catch in the accelerator cable, but I have a suspicion that there is not gas in the supercharger or it needs to be warmed before it will work. CCM

The throttle should work at any engine temp. So does the cable feel stuck? Or does gas pedal move down but it wont rev up? Any check engine light?

No check engine light.

Engine does not rev when accleleator goes down until engine warmed up for avout 5 minutes at 37 degrees outside temperature.

Already gave donation, will give more if it works. CCM

Does this car have a throttle cable or is it "drive by wire"? The only thing I can see that could stop it from revving would be the traction control system. You may need to have the PCM scanned for codes even though the light isnt on. Sometimes they will record short term failures in the"freeze frame/failure records"
