If you can adj to .7v. The afm is ok. If afm no good. You can not adj to that volt at all. If you have 500rpm in gear. Engine not stall. ok. Time to fine tune the system. Check the duty cycle at 2000 rpm adj to 30%to40% from eha. re set idle duty cycle to 50% +- 5%. You need set the system to engine cond. You put new part in older engine. Some time you need to fine tune it. When I change the leaking eha on my wife. Engine run rough till I fine tune eha and idle co.

Andgines,

Thanks for the continued support.

When I was adjusting the AFM, i had left the screws loose and some air was getting in. This increased the idle. Surelythen we need to tell the Idle Control Valve to let more air in at idle?

Whats your take on that.

Please advise

Brian

PS: I havn't played with the EHA valve yet. Do you know if the adjustment is the same as the lean/rich screw. e.g. Clockwise for enrichment, and anticlockwise for lean. I had played with the old EHA valve before replacing it and I got all out of wack.

Try to adj the throttle stop screw. Turn it out 1 turn then turn back in when it contact. From that position turn in 1/2 to 3/4 turn. Try this to get more air in. To play with the EHA L/R is the same. But only do 1/16 to 1/8 a turn each time & re test & re set idle co back to 50% +- 5% and 30 to 40% at 2000rpm. Try this see it work for your car or not. Good luck.
