Flashing engine light is saying that you have a "mis-fire" you need to address. Usually this will be a bad spark plug wire or spark plug. Simple fix. You can do it yourself.

Ignition modules fail quite often causing all sorts of hard to find faults. Parts stores can test these so start there. Have you read the codes set? That may give a clue.

The cam sensor helps the computer determine when to fire the plugs and the injectors which will set the misfire code. Have a trusted mechanic check the cam sensor.

I had a corolla that did this to me, turned out to be an injector. Definitely worth looking towards that.

Ignition misfire, how where the sparkplug boots, they have a tendency to leak toward ground, the coil fail easy and you may need to replace that as well

Cables and connectors to and from the ignition module.
Coil assembly.
Ignition module or crankshaft position sensor.

Have you reset the engine computer since you did the work? Some models have a small wire going to a connector attached to the positive battery cable that supplies memory power to the engine computer. If you disconnect this and leave it off for ten minutes or so, the computer will clear all of the engine codes. (If you don't see the separate wire, disconnecting the battery will do the same thing.) It will also reset its engine parameter information to factory default, so check your owner's manual for what to do after changing the battery to "retrain" the computer for your engine and driving habits.

The coils are the next place to look.

I would replace the spark plugs and plug wires. It sounds like you have a bad plug wire but replacing all of the plug wires and all the plugs should resolve your issue.

I've become SO FAMILIAR with this problem on my own Chevy Optra. The first time it happened, I took it in to my dealer. It cost me over $100 and I SWORE it would never cost me that again. It really IS the fuel system. (Sticking with Shell's "detergent" gas doesn't help!) Simple solution is to add a bottle of fuel SYSTEM cleaner (not just the fuel injector) and the FIRST sign of trouble or with each oil change. No more problems !! "Live and learn and pass it on !"
