Engine Warm Up, Idle Question Options

[Rhodes71/914]

So now that I have my 1.7L with D-jet running I need to do some fine tuning. It's getting pretty cool here now and the last couple of times I have started the engine it has been around 45 deg F and I have to constantly maintain the throttle to keep the engine running. it does start right up though. Shouldn't something keep the rpms up with a rich mixture. I did a some looking on B. Anders D-jet site but didn't really find an answer. AAR? cold start inj? intake air temp sensor?

And the saga continues...

Took the car on a little drive (half hour or so) to get it up to operating temp. After driving for 15 min or so engine started missing, then bucking on acceleration especialy between 2K & 4K rpms, got bad enough that I decided to turn around and go home. This is the first time this has happened, though I have only had the car on the road for a week.

Made it home, small search for idle but pretty steady. Pull each injector connector and each one has signigicant effect when diconnected. Seems that all are firing and getting fuel.

Check compression -
Cylinder 1 - 118
Cylinder 2 - 130
Cylinder 3 - 110
Cylinder 4 - 130

3 is a little low but not horrible.

But... While I was messing with the injector connections I bumped the MPS connector and the car sputtered and died. Engine would start right up but if I jiggled that MPS connector at all the car would sputter and sometimes die. Not a very good connection here and plug slides in and out with little resistance. Compared the one on my 2.0 and it has a lot snugger fit. If i had $400 laying around I would just get a new harness from bowlby, but thats not gonna happen.

Oh and I also checked the CHT and it was 216 ohms when warm.

That's it to this point, turned my attention to the 2.0 and pulled the heads, pics on my other thread. My 2.0

Matt - not sure how the heater ground is going to play out but i will definitely update as I figure it out. Like the lipstick idea.
