Flashing check engine light
Recently I've been getting a flashing check engine light accompanied with a rough running engine for a few seconds under light acceleration, med-high rpm, low speed and lower gears (1st, 2nd). The engine begins to smooth out and the check engine light eventually goes out after a few seconds. Just an intermittent problem, and no associated codes. Any Idea whats going on? Thanks in advance.

had the same problem a bit ago, might be a bad plug wire - I have since changed both plugs and wires, and no check engine light.

Re: Flashing check engine light (Dicecal)
The flashing light is indicating you've got a misfire happening, then as it clears up the light goes out. There's not a code associated with it, but if you have access to Autotap or something similar the PCM keeps a history of what cylinder the misfire is occurring at.

We just had a car in yesterday that actually had a broken pushrod (looked like it had been bent for awhile) that caused the problem.
It definitely helps to have a scanner to narrow it down for you!
