    MAP hose connects directly to the upper intake via a barb on the underside.

      the EGR cooler lines have 2 ends. One is down on the lower manifold in the corner. The other connects to the steel pipe running under the upper manifold on the passenger side. Both need to be capped off, and if you're doing it you should seal them as close to where they connect to the engine as possible, otherwise you've still got the hose that can fail. Or just replace the hose if its working otherwise.

        Thanks guys. So the car seems to be running a lot smoother with the PCV connected. Who knew?! The EGR cooler lines is my next point of concern. I was watching it today as it warmed up and the leak seems to be coming from the lower hose of the EGR cooler line. First question.. Would it be enough to cap the line at the throttle body connection and zip tie the hose to the other one and leave it? It's kind of a lazy approach, but I only bring it up bexause it seems like the hose goes to upper manifold in a place where I won't be able to reach it. Also could it be something as simple as the hose not being clamped properly at the right spot. I let a guy work on my car who I probably should haver thought twice about that looking back. I'll try moving the clamp a bit durther down the hose first. Also will any cap fitting do for this line. Dies anybody know the diameter?

          probably not since the hose is likely the issue. You may be able to just trim the end off the hose and re-attach it though. Pretty sure its 5/16".

          The upper really needs to come off for decent access to these things.

            When I bypassed that on the 88 I used to have, I pulled the short hose from the lower intake and connected the long hose to the EGR spacer to the lower intake. Then used the short hose looped back on the EGR spacer to make sure there was no leaks should the gasket on the egr spacer have any issues internally. I did have to trim about an inch from the end of the long hose for some good hose to seal on the barb.

              My '87 had the EGR cooler lines just hooked together with a heater fitting between the two lines. I ditched that while I had the upper intake off in favor of just looping a single line from the intake to the heater pipe. Not a fan of potential leak points if I can help it.

                Thanks for the suggestions guys. I'm unsure of which route to go with the EGR line. It seems like the easier route would be to replace the hose. I don't know how comfortable i would be with the delete option as to I'm not the most familiar when it comes to mechanic-ship. I'll do some more research here to see if there's a good walk through available. I'm going to pick up a shop manual to help give me a better understanding of the car. I am so ready to drive tbe car again!

                  I've been running without it for years, but honestly it doesn't seem to make a load of difference installed vs not installed. Many people have problems with it leaking with larger throttle bodies and such and its just easier to make it go away in those situations. Most importantly it needs to not leak coolant, so however you accomplish that is a win.

                    Okay. Here's where I'm at now. So I found that the lower EGR cooler line had a nick in it near the throttle body. We were able to cut the hose a bit and reclamp it without having to replace the hose. Now there's no more coolant leak especially when it gets to temp. But I am noticing a significant drip of brownish water underneath the car near the oil pan. I touched it and smelled it and I think it's water. Any clue what may be going on there? Could it be from the earlier leaks when it spewed out coolant? Also my idle issue is still there somewhat. So the car starts up fine the 1st cold start and idles normally. I took it for a spin around the block then left it in park in the garage until it reached temp. I tried changing through the gears to see if it would idle out but it held idle well. Once I turned it off and tried to start it back up it would turn over but not hold idle. I tried to start it a third time and pressed the gas a little bit and then it held idle like normal. I tried it a few more times and it seems to be pretty consistent with the need to give it some gas until it can hold idle on its own. Any clue what's going on there? Maybe fuel filter? It was changed last year but it's been sitting with a tank full of gas for about 4 months

                      could be old leaks, could be weepy freeze plugs, could be a hose or other leak. Gonna have to trace it. Pressure test will likely tell you much.

                      If the coolant is brown thats not a good thing

                        I dont know if its already been said but have you checked your coolant temperature sensor? Both cold and hot?

                          Update:
                          Yes the coolant temperature sensor seems to be working okay under cold and hot conditions. The leaking coolant or water seemed to have stop now. I havrn't noticed any considerable puddles. My friend thought it might have been condensation from the car sitting dormant for so long from repairs and not running it consistently. The last issue is the idle bottoming out. I'm an initial startup, it starts up fine and runs fine with a good idle. Once it reaches operating tempurature and it is turned off anytime after that. On the next startup immediately after, it will turn ovee fine but it won't hold idle on its own. If it is given about 15-20 minutes of off time, then it goes back to an initial state where it starts and idles fine. Any clue what that might be? Thanks guys

                            Dirty or sticking IAC might be something to check for. Does it stay running if you keep your foot on the accelerator?

                              Good idea. It does stay running with acceleration.
