jonost24 Posted March 14, 2009 Share Posted March 14, 2009 My 90 is fitted with a 3.5 Efi (flapper) and 4 sp auto from a RRC about an '88 vintage. When it's warmed and you're waiting to pull away, on light throttle or just as you go from nothing to some throttle, the engine revs dip to the point of stalling, and on the odd occasion it has died but has re-started fine. When the box is in reverse there is no dip in revs when touching the throttle. Anyone got any ideas ?? Thanks in advance, Jon Quote Link to comment Share on other sites More sharing options...
dirkthe1 Posted March 15, 2009 Share Posted March 15, 2009 is that not just the idle set too low? Quote Link to comment Share on other sites More sharing options...

jonost24 Posted March 15, 2009 Author Share Posted March 15, 2009 When the box is in neutral the engine revs ok, with no dip in revs just as the pedal is applied. It just seems to be in Drive, but not in reverse. Quote Link to comment Share on other sites More sharing options...
