FORD AEROSTAR COMPRESSION PROBLEM

1997 Ford Aerostar • 19,000 miles

Getting #1 and #6 misfire code. Changed o2 sensors, plug wires, plugs, air cleaner fuel filt. Is the code more likely to be due to coils going bad? It only codes under load approx 55 - 60 mph or more likely to be compression problem?
