Another new guy question, diagnosing a rough running engine Options

[A Havland]

Hello all. Finally saved up enough to get a 914. It's a 1974 2.0 in silver. I am working through a few issues. When I first got the car home it was hard to start so I did a valve adjustment and now it starts right up. The next hiccup is the engine runs very rough just above idle until it is completely warmed up. I checked the AAR valve and it seems to open when the car is cold. I took out the air sensor and it passed the olms and vacuum test. Replaced the plugs but the old ones looked good. Light grey in color. I could use some help if anyone knows where the two wires in the white connector goes. This is all new to me and the learning curve is steep (at least in the beginning). Any help would be appreciated. Thanks.

Oh, oh, . . .

Now I wanna’ change my answer; I’m going with TS1. I didn’t realize that connector shape was the same as the injectors. I think that is closer to the right location and like the cold start injector wouldn’t seriously affect the engine just running.

Clearly I have no idea and I’m just guessing (IMG:style_emoticons/default/lol-2.gif)

But for OP; this is sort of how it goes, some basic knowledge (ie white = fuel injection) and then some deduction / process of elimination. You’re going to have to do some looking up on the plenum at TS1, the cold start injector, etc and see what is missing a connection. Use your phone and/or an inspection mirror to see better under the tangle of hose, wire, and intake runnners that make head on inspection difficult.
