Hope this helps anyone who may be having the same problem. After replacing the OVP and Coolant Temperature Sensor, it turned out to be a faulty coil and green mold that had grown on the inside of the distributor and coil while the car sat this past winter in the garage. I did not at first check these two items as I had replaced them less than 2 months prior to taking the car off the road for the winter. Cleaned the distributor and rotor, replaced the coil and the car runs perfect. What a relief.
