the EGR system is not active at idle.
Vacum leaks?
You can pull one plug wire at a time from the dist cap to see if you can isolate which cylinder is dropping out.

no vacuum leaks. each wire pull out drop out the same.

 

Grab up your room mates toothbrush and a can of Berrymans B-12 carb cleaner, scrub out around the throttle plate, then you can also pop off the IACV and blast it out with the cleaner, and compressed air.

Pull off the vacum line to the fuel rail pressure regulator to check for raw gas in the line.

A quick way to clean injectors is to run the RPM up to around 4000 then pinch off the vacum line at the regulator with needle nose pliers and let the throttle drop back to idle. [high pressure flush] then let go of the vacum line.
