Idiot Lights

Do they all come on at the same time for only a few seconds? If so it sounds like it might be running the dash test, like when you turn the car on (Turn your key to run from the off position and see if the dash does what your describing)... Could be indicative of a loose ground,loose battery cable, or faulty ignition switch.

Thanks for your response. Yes they do come on all at once. They don't stay on permanently, they sort of flash on and off or varying lengths of time. They seem sometimes to respond to the accelerator but I can't be sure if that is real...

Sounds like a loose wire or a faulty ignition switch, good luck finding the problem... I'd start with cable going to and from the battery.

Thanks, I will give it a try...
