Mitsubishi Repair: 2002 eclipse spyder v6, eclipse spyder, body assembly

Question
the car cranks fine, but when it goes to idle it will shut off.  if you rev engine a few rpm's it will run, but take your foot off the gas and it goes to idle and within 15 seconds it shuts off. any suggestions?

Answer
Ken,
You probably have an air or fuel supply problem.  You can first have some regular maintenance items replaced; like your fuel filter, air filter, and spark plugs.  If replacing those maintenance items do not help, you should then have your mechanic inspect your fuel pump, fuel injectors, throttle body assembly, and the ignition timing.
Good luck!
