Genuinely curious, what do you actually expect any of us to do with that information?
What are you expecting here?

If you don't have a code reader, go to Autozone or someplace like that and get the code read.

Tell us what the code # is.
You can also Google the code # and it will give you an idea of what may be wrong, if anything.

BTW, how about filling in your profile so we know what you drive and where you are located?
That comes in handy when something applies to your location.

What, you can't figure out what is wrong based on that info?
It's pretty clear.

1) He has a car.
2) It has a problem.

pretty basic

This is like trying to do neuro surgery in the dark... dude we have zero idea how to help you.

0 car details
0 location details

pretty much what rtv said... you have a car it has a problem. We cant solve issues in a vacuum.

LOL, right! But in all seriousness, not to beat a dead horse. We can assist you if you let us know what you drive and what CEL code you have. Like stated above, go to Auto Zone, they can check your ECU to see what the CEL code is. Write down the code, and go from there. If the problem is not that big, the Auto Zone staff could possibly fix it there if you like, or you could search on NASIOC if they are unsure what to do. More than likely, someone else on here has run into the same problem. You have to help yourself out, so go from there.

Well, I will assume that this was in a 1919 Ford Model T. These cars were not equipped with factory indicators so I'll assume that this was a Wesson Model 3844 air speed indicator lamp. As you may know, if a human exceeds 30 mph, he will be unable to breathe, so this indicator lamp shows that you were perilously close to hitting 30 mph. You need to drive your horseless carriage at a rate of speed that is lower than you have recently been attempting.

Due to lack of details no concrete conclusion. However I have one thing for you. STOP!!!! Park the car. A flashing CEL is a warning that a severe misfire (or other condition) exists that is dumping fuel at a rate raising the temperature of the catalyst that will damage it at minimum.

It could be as simple as a fouled plug. As serious as major component failure. Have the code read and report back. But do it without driving the car.

Ok yes SHE is a noob.... Getting live help is even more difficult then you all.... So its a 05 impreza wrx almost 180000 on it... Not sure what all has been done I've only had it a couple months.. But he was running perfect earlier in the day, went out a few hours later. Then this... I drove it right back home maybe a 1/2 mile checked all the fluids, changed the plugs today, waiting for my son to bring me a scanner

Flashing usually means misfire.

First, make sure that the electrical connector is securely on the ignition coil at cylinder 2 (Front driver-side). If that's good, then I would suggest swapping the #2 ignition coil with another ignition coil, I would suggest cylinder 1 (Front passenger-side) because it's easier to get to. Connect everything back up, and start the engine up after the swap, if the misfire follows the ignition coil, then that's your problem.

So changed the plugs and the #2 coil, still the same!!!! The light went off for a min, then went to just on Not flashing, for it up to temp then started FLASHING again? I think I can hear a little tick, but not like a no oil tick? Someone suggested maybe something to do with the turbo? IDK?

Okay, so you ruled out the ignition coil and spark plugs. Clean out your MAF amd O2 sensors. See if that helps, and please update us.

Drop the exhaust and look to see if your valve guides have dropped.
