Rough Idle and Throttle Response

Rough Idle and Throttle Response
I have a 1987 F150 4WD 300 I-6cyl. It has a rough idle and rough acceleration as well. I have done a compression check which is good. I have replaced the plugs and wires. While the truck is running you can remove plug wire #1 and the truck idle does not change. The plug wire is getting plenty of spark when grounded to the engine block. The only thing that I can think of is the fuel injector on #1 cyl. Any thoughts? Like I said the compresion is good and the cylinder is getting plenty of spark. A friend of mine had a Toyota that did the same thing. He removed the fule injector, cleaned it and it fixed his problem. Any help would be greatly appreciated.
