Since I've rebuilt my '74 2.0l FI engine I've had problems with the car not idling. After it warms up it dies. I've set the timing to 27 and the dwell is at 46. I tried adjusting the ECU knob and the air idle screw but neither appear to have any effect on the idle. When I adjust the knob I can feel it click. I counted 21 total clicks. The engine runs great above idle. The injectors have been rebuilt, new AA vacuum hoses replaced, all gaskets are new.
Can the ECU be taken apart and cleaned? Does anyone have a pic of the ECU opened up showing the knob area? Any recommendations on how to fix the idle problem I'm having? -- Rob |
