Hello, I'm Mark Hall, and I have a Chrysler Concorde 93 (close enough to 1st gen intrepid :-). Car has an intermittent problem - will shut off when driving. All guages go dead (lights stay on!). 2 times this happened and I was able to restart while in motion (kinda scary on interstate). Seems to die when slightly letting off of accelerator. On 3 occasions came back to car after parking for 30 minutes, and would not start even though battery was strong and cranked vigorously. Eventually fired up just fine (5 minutes of intermittent cranking). Not a flooding problem (no smell and very little throttle applied during cranking). Last night ran very sluggishly, seemed like only 2 cylinders were firing. But when I *reduced* the throttle, it would perk up again, then bog when I added more throttle. Seems sensitive to wet weather (and I live in Seattle, so that's a lot). Engine codes were 12, 21, 11, in that order. The above list list of codes is very helpful, but where should i start? Any instructions to replace sensors? Thanks!
