Question about Cars & Trucks
It could be the co2 sensor, but have you thought of having a cylinder leakage test done?? A competent garage should be able to perform this test for you. Basically they pump compressed air into each cylinder on the firing stroke, in turn, to establish that all is gas tight. If you have a broken piston ring or leaking valve, this will show up as a leak and could explain the rough running, especially on number five.

plugs and or wires.
for some reason the spark is jumping out of the wire or plug.
the plug insulater may have a crack in it.
also use a carb spray to clean out the throttle body at the throttle plate.
all the black carbon will build up around the throttle plate and restrick airflow at an idle position.
hope this helps
