Volvo Repair: lights intermitant flashing on dashboard, volvo dealer, fuel injectors

Question
Hello,
my 1998 S70 is flashing different lights on the dash for only a split second at a time.  I cannot even tell what they are flashing only the color.  Sometimes it is a red light and others it is orange.  I took it into the Dealer because it also sputtered sometimes at a stop light.  They said the fuel injectors, filter and spark plugs had to be replaced.  I paid for it and within 10 minutes of driving home, the lights came back.  It stopped sputtering but do I just ignore the lights because I cannot afford another bill like that for a while.
