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?

You failed to mention of you tested the vaccum cannister on the dizzy for leaks. The cannister is of a single diaphram so plugging one side isn.t a valid test. To test it ....you should pull vaccum like your MPS with either side capped and pull vaccum and see if there is leakdown.
If this is leaking your car won.t idle right and timing won.t be correct either. |
