to stop the noise from returning, simply disconnect the electrical connector near the antenna motor (follow the wires out of the unit). this unit may be disassembled and thoroughly cleaned (especially the copper electrical contacts) to restore it to near new condition sometime in the future....about 3 to 4 hours for a novice.the clicking is due to the motor "coming alive" when an electric signal can get through the oxidized contacts. prolonged "clicking" may not harm the unit...there is some chance the antenna's nylon gear track has separated...try to pull up on the antenna itself after disconnecting car battery. if it cannot be pulled up, then chances are good for earlier described restoration. if motor housing looks VERY corroded, a full replacement of unit is best sol'n.

it is very easy to replace it. fint it near enginen. remove old. pick full of fuel new filter and turn on into the old filter place.

If you checked as suggested for vaccum leaks and have no improvement or only little... Assuming here its KE-Jetronics fuel injection.... on the excellerator linkage is a microswitch that gets activated when the excellerator hits idle position (decel fuel shutoff)... it has an influence on your idle quality, also the electronic component in your air/fuel mixture body (Airflow potentiometer) could be the 'guilty' party aswell as your Idle valve (on single belt engines) that is stuck between the inlet pipe of number 3 and number 4. Anyway i hope this helps to locate the problem

If the fuel gets to the distributor but no fuel comes out of the distributor if the airflow disk pushed into the air/fuel mixure body, i suggest you check the electro-hydralic-actuator
Its the black box (picture thanks to elproboscis from ebay america) as it controles the flow to the pluger body inside the centre of the distributor and goes from the plunger direct to the 4 outlines.
