By the way, my recent problem seems to have been corrected by adjusting my Lambda Tower Screw. Going clockwise richens the air mixture and will cause gas and acceleration issues but might idle great! Anti-Clockwise will cause idle problems with eventual shutdown. if this happens turn screw back a quarter turn at a time and try to restsart. I had to make 1/6 Turns close the hood, drive the car, repeat, until I got it to accelerate with no hesitation. By the way, leave the air housing all intact while doing this. The idle went back to being just not so perfect but I think a defective EHA valve could be causing this this??? I put new plugs, new cap, rotor, and coil in. Any takers?
