Hi Guys,
It has had an annoying skip while cruising for some time now. It was flashing a code which said o2 sensor, so I replaced that and it seemed like it was fine on our trip to Nashville for the first 50 miles or so then it started again. You can only tell that it is skipping when cruising. If you get on the throttle a little bit it goes away. I have replaced the wires, distributor cap, rotor button, plugs and now the o2 sensor, to no avail. Any ideas?

What size van?
What was the code no?
02 sensor codes do not flash.
A misfire flashes check engine light.
Check engine for misfire.
How is fuel pressure?
Has camshaft retard been checked?
Was good AC Delco parts used?
