idle surge

Okay new update- replaced the main breather hoses and idle control module. My rough idle is actually gone in drive or is almost invisible. However the idle at P is still weird it is not lumpy any more but surges starts at 600 then slowly increases to about 800 then drops to 600. AC switch works as it should, rechecked for vacuum leaks none showed up. I am at a loss. My next step is the OVP relay. Anyone got ideas?

So far changed:
All the engine rubber (needed to anyway all brittle)
new plugs, wires, rotors and distrubutor. (needed to original)
new injectors with seals (original injectors)
new idle control module. (not sure if I needed it but got one cheap on ebay in original sealed package $25 thought it was worth a try unfortunately no effect.)
