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?

Clean all the effin FI connections and re-connect with a dab of dielectric grease on the prongs.
I think you are suffering with several issues mostly grounds and weak connection. Wrap black electric tape around the MPS connector to hold it in place securely. Make sure all the grounds (battery-, tranny strap, under the relay board, FI block on the engine) are polished shiney with a dab of the grease. Check the ground strap in dizzy to make sure its attached properly. Check the advance plate for movement. Your compression numbers indicate that the valves are worn so cold starting and warm up are going to be alittle rough. Bucking is usually a worn or out of adjusted TPS. Could be just the weak spark too. Geoff |
