jtpaintballwdp Posted January 16, 2005 Share Posted January 16, 2005 To replace the vacuum lines in the dash, do i need to remove it, or is there a way to get to them w/o removing it? My car has a rough idle (when cold, and little less when warm). I have replaced all other vacuume lines under the hood and retimed it to stock timing. Any other ideas would be very helpful.

Guest Cronic Posted January 17, 2005 Share Posted January 17, 2005 The dash is very simple to remove, just be careful not to crack it in the process. I believe there are only about 4 bolts and 4 screws holding it together. Quote Link to comment Share on other sites More sharing options...

technicalninja Posted January 18, 2005 Share Posted January 18, 2005 If your trying to diagnose a rough idle issue the HVAC vac system is not going to be your culprit. You can isolate (disconnect) the complete underdash system at the intake manifold (1 single small vac line supplys the entire system) it goes directly into the plenum about 3/4 of man length from T. body. Some years are different for location. Disconnect line and plug fitting, probably will not make a difference in idle. What year is your car? All vacuum lines under dash can be replaced with out removing dash. Quote Link to comment Share on other sites More sharing options...
