I am working on a 90 Camaro 350 TPI. I just replaced the injectors and think I may have crossed a couple of vacuum lines. It is idling almost like it has a miss. Can anyone tell me where the vacuum hose from the throttle body goes to? Also, where does the line from the vacuum canister(behind drivers side headlight) go to? Also, the 2 lines that come off the EGR solenoid? I have following the vacuum diagram as best I can but want to double check. Thanks in advance.
