When I drive on the highway or at speed (around 3000 rpm) the tach starts to "TICK". It bounces up to 4000 rpm and then back down to 3000 RPM. There is no pattern to the bouncing ...its random!
ALSO...I know sometimes the alternator causes the tak to do something like this....my alternator is new so no prob!
It all started when I installed a used distributor to replace my old one that went bunk!
Here is what I notice...when I'm flooring it around 3000 RPM and the needle starts to jump around there is a change in engine power. SMALL...but a change none the less. I think this is related to timing?!?!?!
When the needle starts to bounce the ignition timing is changed.
Is there any way the ignition timing from the dist and the tak signal are related?
