It does make you wonder how much of those D-Jetronic issues were things like simple ground faults and how many were failures of the analog electronics. As long as they didn't act up, one of the main selling features for the average owner, especially of the female persuasion, was that you no longer needed to fuss with a choke.
Yes, I should have said CI (Constant Injection) fuel system, not CIS (Constant Idle System).
Just for jokes, I dug out some old 1974 140 brochures I've had buried. They talk about the new and improved "CI fuel system (Continuous Injection)" being introduced into the GL models with no mention of the word "Jetronic", probably preferring to avoid any association with the previous D-Jetronic electronic issues in the E/ES models.
To quote one brochure,
"The GL's two litre fuel injected engine runs on regular grade gasoline. Without carburetors. Without a choke. For '74 a new fuel injection system is introduced. It works on a principle of constant injection. As engine speed increases and more air is inducted, more fuel is injected. It is as simple as that."
1974 was also the year Volvo introduced the big square safety bumpers, the first incarnation of SIPS (Side Impact Protection System), the gas tank more safely positioned above the axle, an electrically heated driver seat and child-proof rear door locks.
Possibly the biggest weakness of the 140 series was rust. Probably the #1 reason you see so few of them these days, far worse than the 240s.
