RE: Moment of weakness...
Incidentally, I'm also having problems with my '82's 1.7. It won't idle
when cold, and when warm, at constant throttle and load, it surges. I
disconnected the O2 sensor, and it ran rough, so I reconnected it. What
effect should I see (or what am I looking for) when I disconnect the
frequency valve?
