I was helping Matteyp tune his car last night and it's the first time I have worked on a fuel injected engine. We got the dwell set and the engine timed with the light, it's running better but when I tried to adjust the idle speed the adjustment screw didn't seem to affect the idle speed I gave it two full turns in each directions. My questions is how sensitive should this adjustment be?

James did we have that vacuum line plugged when you were adjusting that screw?

QUOTE(matteyp @ Jun 21 2011, 09:51 AM)  James did we have that vacuum line plugged when you were adjusting that screw? Yes, it was plugged, after we adjusted the timing I placed it back on. The last time we ran the motor I tried adjusting it. After you get the valve cover gaskets replaced I can come back over and we can try to dial it in a little better. Jsaum |
