What codes did you get or are stored? Do you have an automatic? When you say started running rough, how?

Blinking is usually a misfire code. Only way to know for sure is to pull the codes.

You would need a good scanner that has the ability to look at MODE 6 codes. Will most likely give you a misfire code.

The CEL only flashes for a misfire event.
The issue cleared up, light is off.
Can you duplicate the issue? If so, light will likely stay on the second time.
You have a 20 year old car, any number of issues could cause a missfire.

Without a proper scanner to pull codes we are all guessing... (ignition coils, bad gas, etc.)

I understand that. With the proper scan tool that can do MODE 6 it can possibly pull a pending code to give you some direction.

Sometimes your CEL will flash for transmission faults also, that is why I asked what kind of tranny you have.

Finally got a chance to check for codes. There are no codes

What type of scanner? Does the scanner offer "Mode 6"

Again. Did it offer "Mode 6"? It gives you deeper info than a standard scanner.

sorry idk what mode 6 is it does show live data with no problems

Mode 6 is designed to help diagnose problems even beforea check engine light occurs.
