Thought it would be obvious, but cannot find an easy way to adjust the idle on a '73 with D-Jet? It runs fine until it warms up, then it idels at about 100 RPM - when it stays running?
Thanks |

1st....Buy a Haynes Manual (cheap).
2nd...there is a idle screw on the throttle body (location depends on whether you have a 1.7 or 2.0). This is used to adjust the idle on a fully warmed up engine (the AAR has closed and is no longer supplying additional air) 3rd....on your ECU you will have an idle mixture knob...intially set it midrange. 4th.....Check your timing and the rest of the ignition settings. (see #1 above) 5th....Check your fuel pressure (see #1 above) 6th....Check the valve adjustment (#1) |

#1 problem is that guys adjust the idle speed with the AAR valve partway open, the engine only warm. Engine heats up to operating temp and the AAR valve closes and Bingo! idle speed is at 300 rpms. Huh (IMG:http://www.914world.com/bbs2/html/emoticons/mad.gif) You can just plug the AAR valve hose and then set it...but thats cheating.

But it will tell you if you have a GOOD AAR or not! (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) M |
