So I did a bearing job on my 81 245 and got the engine back in the car and now trouble hath reared its ugly head. When I first fired her up I couldnt get her to idle for more than a few seconds, running rather rough I could feather the gas and keep it running long as I wanted, didnt need to give it much gas either, just enough to get it to above idle.

Father in law comes over to look at it for a second set of eyes. He sees that one little vacuum-ey looking hose that I believe is for the flame trap venting (the hose underneath the intake that just hooks over into nothing, its on the vacuum diagram as such). He plugged it and now it went from barely idling to now idling at really high rpm, earballing I would say bout 3000rpm or so, even after unplugging the hose.

Now if that was indeed the flame trap it shouldnt of had too much of an effect as I put the valve cover and flame trap setup from my '79 244 on there, so there should of been plenty of venting going on. Then I went searching for vacuum leaks, spraying starting fluid around, yet couldnt find anything. No intake leaks or injector seal leaks either (injector seals are new)

Two things of note:

Theres one wire that may solve all my problems, I cant find anywhere it hooks to and dont remember unhooking it so it may be superfulous. Its the double green wire in this pic:

the other is a wire I also dont remember doing anything with, its a eye connector by the cruise control, tis a lil bugger
