Well after jacking around with this idle for ever now (TPS sesor, set timing a couple of times, AFC adjustments, etc) it should be cured now. Sent Jeff my ECU for the Keydiver chip mod and he noticed that there was acid damage to the board at the ISC driver. Didn't notice it when doing the caps last year. DOH!!!! How many times has he told us about this and I just didn't think that was it. Thanks Jeff!!!
