You have a couple of posts for the same car, keep them together, it makes it easier to have folks help you. A flashing check engine light indicates a mis fire, you may have plugs that need replaced, wires that need replaced, ignition components etc. Your other post asks about gumout, gumout won’t fix a mis fire ---

Since the check engine light is flashing, that would mean codes. Have them retreived and post codes on here. Not the definition, but the actual code/s. ---

Kinda looks like problem with number 6 injector and/ or wiring for injector. using something for a listening device like a long screwdriver, listen to the injectors. Chances are number 6 is silent. ---

That code is from an electrical malfunction of injector. Either wiring, shorted injector, or possibly even bad PCM. Snake oil is not gonna fix this one.
