Hi hows it going? This is my first post here sooo dont mind my spelling lol. I just got a 86 trans am 5 speed with a 305 quadra jet. I have lines not connected and stuff everwere in the bay ( car is runing) Im not sure if anyone has some pointers to get this thing runing like it should? and if theirs anyone around naperville il that likes to meet up with these types of cars let me know!!
Some pictures of the engine would be nice so we can see whats connected and what is not connected.
Otherwise refer to the vacuum/emission routing diagram on the underside of the hood. It shows your a basic map of where everything should go.
If you have open vacuum lines theres a more then likely a massive amount of non-metered oxygen getting burned which can cause really poor fuel mileage and performance.
The "Air Injection Reaction" system, aka, "A.I.R." system has been removed. That's what the connector in your first picture is for,
The air conditioning has also been removed. May not be too pleasant during hot Chicago summer days. The solenoid in your third picture is the idle "kicker" solenoid, to bump up the RPMs when the AC is turned on. Since your AC isn't functional, no big deal. The solenoid is also activated by the ECM during certain deceleration conditions to reduce emissions, but it isn't something you'd notice as a "running like it should" thing. Go ahead and reconnect it, won't hurt anything either way.
The vacuum port capped of in the upper left corner of your third picture is for the stock air cleaner. The open element air cleaner on there now doesn't need it, so it should be capped off.
Some more pictures with the air cleaner removed would also help. Particularly pics of the front and passenger side.
alright so far not to bad lol well here are some more pictures. Thank your very very much for your input its helping me alot. I dont know much about these style cars lol
