low idle speed

I just picked up a 1990 f150 4x4 with 89,500 miles on it it starts good and runs really good but idles slow maybe 100 rpm slow, it has efi at ac. Also the guy I got from had a remote starter put in at a Ziebart dealer. any suggestions ?

I would start with checking the baseline timing and rpm. A Haynes or Chiltons manual would be a good book to get if you don't have one already.
