Sounds more like a vacuum leak. Is it hard to start when it knocks off?

I looked at d21 pickup--3.0L, my info showed this firing order.

Most likely not, they change designs every 3-6 years on almost every make car. A 1986 probably doesn't have the electronic sensors that would be present in a 1999 vehicle and would probably never work once installed, assuming it would even match up.

For the firing order and wiring routing for the 8 plug 4 cylinder engine: (Plugs on the intake manifold side are coded "I", and on the exhaust manifold side are coded "E")

Wire to 1I should be connected to tower on the distributor facing directly to the front of the vehicle. Going counterclockwise from there, the order is (1I), 2E, 3I, 1E, 4I, 3E, 2I, and 4E.

1 - 2 -3 - 4 - 5 - 6 counter clockwise starting from the #1 plug it will be maked #1 and the #1 plug is passenger side front the firing order is also stamped on the intake manifold.
