replacing variable resistor
i was looking in my chiltons rx7 guide, i had read that if you replace the engine, you need to replace the idle fuel contol variable resistor(if thats what its called)
I checked it with my meter and it was within spec, but when i turn it, it seems to do nothing. is it still good or am i looking at a trip to mazda?

If you read the Mazda manual is says Tamper proof for the resistor, and that's why it is supposed to have a wax covering over the screw. There are no adjustments available for that in the manual. Now from experience my 87TII had the cover missing and at the time I turned the screw back and forth and didn't notice a difference either. So I couldn't tell you what the possible effects of doing so would be.

and if you find out what the specs on it are then...you can just use a regular variable resistor (like 50 cents) as opposed to the mazda one that probably cost like 20 bucks

i did actuallly follow the fsm, jumpered the connector and nothing seemed to happen. is it supposed to be a noticable difference? i have an air/fuel gauge(narrowband) and it doesnt move a bit when i adjust it.
