Pulsing At Idle Options

[Jim C]

Want to see what the World thinks of this. I have a 1976 2.0 with FI. Injectors have been cleaned and checked, ECU repaired, CO checked, trigger points replaced, valves adjusted, timing set, but at idle it goes from barely running to 1000 RPM or so in a rhythmic manner. Also, when accelerating you can feel a momentary drop in power. Thoughts? (IMG:style_emoticons/default/confused24.gif)

Absolutely check for vacuum leaks first. But based on this:

"Also, when accelerating you can feel a momentary drop in power. Thoughts?"

I would also check the calibration of your throttle position sensor. If the sensor isn't set properly, it can cause the car to lose power just as you crack the throttle.

Try richening the idle mixture by adjusting the mixture knob on your ECU clockwise a click at a time.
