That hose was leaking on my new '85 causing very bad performance. I plugged the line at the ALDA, but the car seems to shift more harshly now (could be my imagination though). What does that blue thing do anyway?


You should plug the nipple that comes off the ALDA, otherwise you the ALDA will not be recieving the correct pressure signal.
