the idle revs up from 700 to approx 1000 for a second or so then returns to normal

this happens every minute or two

have cleaned the throttle body, tried a differnt IAC (ISC) and set the base idle

what is the cause of this and is mostly just EFs that do it or is it all E series?

One thing you may want to check is the power steering pressure switch. My EA had a failed switch and it would idle high at random as well as on trailing throttle (which was interesting to say the least!).
