89 XR-7 problems - ignition

My wife has an 89 XR7 with a continuing ignition problem. Based on threads here I pulled the balancer and found no problems. Based on a PIP code (forgot the code number) I changed the cranksensor. The CPS is new, and I switched out another (not new DIS module). Still an obvious miss and occasion clouds of black smoke when idling. After all the above the only code coming up is CID (I think 19) and tach is flat/nonoperative/inaccurate. All this would seem to point to the CPS which I doubt (again it's new). Now I'm wondering about the wiring harness between the CPS and DIS. Any help/revelations or even good ideas would be appreciated. If you want to e-mail direct try jayj@fastfab.com during business hours (east coast) or holtzman@shentel.net after hours.
