The high-idle spped problem also occurs on my '75 914, which has a 1.8-liter flat 4 (basic BUG block) PLUS fuel-injection, among other things. Anyway, the problem is injection system related, and for my car has two related causes: 1) leaky seals on the injectors (too much fuel being injected), 2) a sticking air-flow sensor, which is a mechanical flap attached to a pot. I doubt whether the injection system is the same type (porsche doesn't use it on any otjher cars either), but the causes may be similar. Good luck. john Burgess, BTL Piscataway
