Got the idle problem pretty much licked. I picked up some new fuel lines and in the process of replacing them noticed the number one injector return line was half off and frayed. I snipped and replaced it with a new section. Also I had replaced the check valve with a heavier one six months ago So I went into my harbour freight spring kit replaced it with a softer one. Got the car started air out of the lines and it idled much better. Let it do that for fifteen mins or so put it into drive held the brake and it didn't die but did lurch a bit.

So I cracked each injector nut and the number two didn't give much idle drop. Tomorrow on break at work I'll pull this injector out and clean it up and see. If not then replace the spring in my IP check valve with a stronger one. If nothing still then I'll play with the position of the delivery valve seats.
