Re: [DML] Idle_Off-idle problem

Dave,

There are two versions of the idle speed ECU both are set for 750 +/- 50 RPM when switched on and 900 and 1200 RPM when switched off. Although the 1200 RPM sounds high the effect will null out as soon as a load is placed on the engine.

BTW; your idle speed should be 750 RPM not 850.

Subject: [DML] Idle_Off-idle problem


I was helping out another DMLer yesterday with a problem that has me
scratching my head a little. The original complaint was that the car will
either idle at 850 rpm (normal) or, as you tip-in the throttle, jump
immediately to about 1200+. Makes it hard to make a smooth start in a
manual-trans car. The odd thing is that if you take it out of "idle" mode by
backing off the microswitch adjustment, it will go to 1200rpm with the
throttle still closed. We backed off the throttle stop screw as well, no
difference. No one has ever messed with the A/F adjustment (it is still
sealed, the car only has about 3K miles on it). No obvious vacuum leaks.
Other than this, the car runs beautifully.
