sweetleaf Posted October 10, 2009 Share Posted October 10, 2009 Check you vacuum lines. May have come off at the bottom of the control unit. Quote Link to comment Share on other sites More sharing options...
roger280zx Posted October 10, 2009 Share Posted October 10, 2009 (edited) As stated above, vacuum leaks kill these things. If you want to switch to the later and better system please let me know (shameless self promotion). I battled with worn out diaphrams and dry rotted/missing vacuum lines a long time and a lot of money ago. Then made the switch.
