Safe Mode...?

[Serottab]

2003 C4S Tip, US, ~30k miles. Went out for the Saturday morning coffee / 50 mile drive today. About ten miles in as I was just rolling on the throttle in a mild left sweeper, tha car hesitated as if the throttle cable had parted (if there is a cable...). The car continud to run, no CEL, however with much reduced power. Wouldn't pull RPMs over ~4k, felt like a great feature to engage for the wife driving - The fuel level was down to about 50 miles remaining, I don't know if perhaps fuel slosh triggered some sort of engine safety mode, or ??? Got home and parked it for a few minutes, restarted and it drove normally. A little disconcerting as I don't know what initially caused the problem, or what 'fixed' it. Unfortunately no code reader available (yet). Help -?

Thanks,

Marc

You will need to have the systems checked for codes, without them it will all be just guessing. You can have a code in the system without triggering a check engine light. It's also not recommended to run the fuel tank level so low as it's believed that it shortens fuel pump life from poor cooling and also save the embarrassment of running out of fuel. The calculated fuel remaining doesn't take in effect of terrain and such and could leave to stranded.
