Put in some work today. I recleaned the Idle control valve and in the process managed to chip the lip on the plunger inside... guess I need to order a new one. I also removed the fuel distributor and cleaned that out some. While I was at it I pulled the OVP relay and a few others down there. the OVP showed some corrosion which I cleaned off with a wire brush then resoldered all the connections. I also adjusted the mix a tad richer to bring the idle up a hair to around 7-800 rpm. net result: car is still hard to start, now it still takes about 10-20 good cranks to start cold and about five to start warm. I noticed some leaking around the fuel line on the side of the distributor and tightened it down. (the thick line closest to the front of the vehicle) it's possible I may have bent the line a little trying to line it back up. (didn't notice the 10mm bolt holding it in place) so tomorrow I will pull the air cleaner and make sure it's sealed up real good. The stalling when put in gear has diminished considerably. I did notice a new symptom that first showed up a couple of days ago but is more pronounced now. While driving at around 50 MPH the engine will bog down for 2 seconds then let up then repeat. It is pretty intermittant but a little disconcerting. Any ideas?
