Rick; greetings, my name is Ken.
If you could, I wonder if you might share some wisdom please Sir.
I recently acquired an 85 D90 w/ a 2.5NA. It is exhibiting a behavior I have not been able to figure out.
The idle speed is quite high; even with the throttle and idle 'cams' both hard on their stops.
Strangely, the idle cams does raise the idle speed, but but only after moving it above half travel.
Other than that, the Defender starts great, is running well, and doesn't seem to smoke at all..
Thank you in advance;
Ken
