I have been fighting the D jet slow idle on my 1971 1.7. Have checked and rechecked everything. Bought a smoke machine. Bought a new timing light with advance. All new ignition parts. Checked MPS. Checked all sensors with ohm meter. Disassembled and cleaned Distributor. Good compression. So started disconnecting things. When i disconnected and plugged the vacuum retard I was able to adjust a 900 rpm idle with the (finally effective after removing vacuum retard) idle air bleed. So I did a search for "914 vacuum retard" and this link came up. Read the last post. Exactly fits my symptoms. I'm going to try what he describes tomorrow and see what happens. But I'm pretty sure I'm on the right track finally. Thoughts?

No adjuster on the ecu. I have a 74 with the adjuster and wish this car had one. I am going to try and order the FI trigger points adjusting tool and try that too. I cleaned them but that was all... I'll post when I get a number on the timing, haven't put the light on it yet just by ear. I don't know how your car reacted to changing the timing but on mine it is almost like a switch is thrown when I get enough advance. Like it suddenly stops struggling then the rpm rises smoothly with more advance from that point.
