Question about 2001 Ford Focus
Idles Rough, Runs okay on the highway. Wants to die at stop lights. Noticeable loss of horsepower. Plugs and wires changed. Fuel pump removed cleaned and tested. Coil pack maybe?
Can you confirm cylinder two is getting spark ?
If it is, it could be something mechanical or the fuel injector.

It could be carbon deposits on valve seats keeping valves from totally closing. You can try getting you a can of motorcraft PM3 top end engine cleaner and get engine up to operating temp then remove one of the small vacuum lines from the intake and draw the contents of the can slowly into the engine.After you have drawn in the contents shut engine off and let it soak for about 45 minutes then crank it back up and let it run until it clears. Now it will smoke like a forrest fire while you are doing this so don't be alarmed,just tell the neighbors you are spraying for mosqitos.This may cure the problem. If not you may be looking at a valve job.
This can be verified with a compression test if this is what is causing it.

remove the coil pack and look at bottom of it if it shows any cracks coil is bad very common on these vans if you have a noid light check for injector pulse on #4 if you have pulse and good blue spark most likely the injector is bad you have to remove upper plenum to get injectors out let me know how you make out

You still need to replace the plugs and wires regardless of the visual appearance. If it persists then a compression test and fuel injector swap is needed. If it persists then more expensive parts and tests are needed to see if it s internal engine issue or lean running issue or clogged EGR port.
