I have a 1993 with a 114K on the clock and the other day the CE light came on while driving. The light stayed on for about a mile and then went off, everything else was normal. Did the paper clip thing today and pulled codes 83 84 85 and from what I can tell this is going to be a $$$ kinda problem :-[ Can anyone shed any light on this while I wait for my FSM to come? Any ideas what triggered the codes? The truck runs great, gets 16-17mpg all the time. The only problem I have found is that sometimes at a traffic light it will idle a tad low, ~400rpm, but that is only on occasion....
Thanks
Steve
