Ivan Posted July 27, 2006 Share Posted July 27, 2006 Have a 1991 V8 3.5 EFI discovery. The problem I am having (and have been for some time) is that I can't seem to get the tickover revs correct. It tends to tickover at about 1100 rpm instead of 7-800 rpm. I have adjusted the allen bolt on top of the plenum (idle air valve ?) which has brought it down some but not enough. The screw has now been turned fully clockwise (I think) which did drop the tickover revs but not enough to bring iot down to the 7-800 rpm it should be. Sometimes just after starting it will settle to about 750 rpm but as soon as I use thethrotle it goes up again. Any clues ? TIA Ivan Quote Link to comment Share on other sites More sharing options...
