Intermittent 'Check Engine' light
When the car is cold, or it's cold outside and until things warm up I get a flash of the check engine light under moderate to hard acceleration. If I take it easy, no light.
And there are no codes stored that I know of...
Ideas?

I wanted to bring this back up because it is happening in my 91 'vert.
Only comes on when "cold" (around here that's about 50 degrees or so) and you put a load on the engine. Mild acceleration yields no light, and after a while it doesn't happen. During this time the water temp gauge (as useful as it is on the S5) is reading at "warm" (middle of gauge).
Anyone come up with some new info?
