there was a vac line on the back of the intake manifold that was not mentioned in the fsm, i was unable to reconnected it(yet) b\c the 17 year old vac lines are hard as rock, what is it for, the car wont idle now so i imagine thats the problem, i also was unable to reconnect the 2 subzero starting line, which it never getts cold enough anyways, but would they effect it? the car will stay stedy at 1.1k rpm with me holdin the gas in a little, and damn its fast up from 2.5k to 7.5k, i can tell really well, but i kinda would like it to not die when i left off the gas ....

 

16 veiws and no replys?, no one knows what that one vac line is for?, thanks

 

Take a picture. You should also just remove the subzero assist as recommened by mazda I believe.
