It´s been flashing for the past 2 days. It's an automatic. There is a button O/D but i rarelly use it. Now it is flashing. Can anybody tell me what is it? I also noticed the speed dial is not working just today!
I brought the car to portugal and they don't know much about it here!
(For those asking: i saw this question already- I asked in the wrong country...dahhh!!! sorry)
As "rcend" said, it mefires aswell when i started this morning. I thought it had nothing to do with it. As for checking speed/RPM i don't have the speed clock working also. The idle has come down to well below 1 as it was not normal.
You guys are being very helpfull anyway thanks.

With all the other problems, I'd say you have an electrical fault. You'll need to find a good vehicle electrician. Mind you, if you're particularly agile, delve behind the dash and see if there's a loose connector in there.

Its Over Drive, Maybe The Fuse Is Blown Up Check It Out

It's your Over-Drive. Push your O/D button and see what the light does then, it may need to be serviced.

That button is the Overdrive button. Try pressing it and see what happens. If the light is flashing it may indicate the top gear has failed and cannot be activated, but this would be strange. The light should tell you whether it's on or off, you should feel another gear with it on when you go to higher speeds. It would be unusual for it to fail, could be a dicky bulb. Set it so the overdrive gear is on, then take it for a spin and count the gear-changes. If you have 3 gears and it's revving around 3500RPM at 60MPH you have a failed overdrive. You should get 4 gears with this though and at 60MPH you should be doing nearer 2500RPM.
