    When CEL flashes it usally is detecting a engine missfire. When the CEL flashes it also means you should have checked ASAP due to the fact that continued driving with an missfire can be damageing to the catalytic converts.

    Could be any nuber of things, scondary ignition, spark plugs, leaking intake manifold gaskets are common faults. Have seen a couple with broken valve springs.
