Car quits running normally, then starts running again

It has new spark plugs and wires. Also new fuel infector #1 was installed

How was it running before the ‘infector’(injector) was replaced?

No. One cylinder was not firing.

Car does not stall completely and this usely happens while driving down the road. Then it will be OK for awhile and then all of a sudden it does it again.

This may not fix it but re-check the plug wires and plugs.

You may have a ECM fault and may have to be scope tested.

Any CEL and new codes?

It seems to me to be more related to something electric than mechanical.
