i'm dealing with a similar prob right now, and totally baffalled myself. we replaced the disty, (thru a shop) and it ran fine for a while then did the same thing again and was just warrantied out, but the third time's a charm

have you checked the h2o? mine will seek like you are describing when the water is low. the computer uses this to determine fuel mix (along with a bunch of other stuff...)
