About 70's EFI. Those are marvellous, when they are working well, but finding reason for any misbehaving, can be very challenging. Some years ago, we had some wrestling with DS 21 IE, of course with hydraulic gearbox, it took some three years before it worked well.


I have one of those. Exact same specs. I got mine in 1999, got it back on the road in 2000. It had been standing since 1982. But in a garage;) Was struggling with off-the-charts high CO, and engine spluttering/misfiring when idling. Found a faulty fuel pressure regulator, miss-adjusted throttle switch and some bad electrical wires. It was almost good, CO could now be adjusted to correct figures. But still spluttered. Every time I opened the hood and put the CO reader in the exhaust, it ran well with nice readings! But when driving it wasnt. By chance I discovered it stopped spluttering when I opened the bonnet, and started when I closed the bonnet. Bought new HT-leads and a 123 distributor. All well after that. Strange though, as the HT leads are well hidden under the intake manifold. Oh well, been working since.
