92 TD27T idle issue

[keepwalkn]

TD27T

After a a drive or power run on the dyno, if I slip the car back into neutral, the idle slowly creeps up to 1400-1500rpm. (was 1200-1300rpm before tune)

With the aircon on, and in drive, the idle is not affected, it will idle up to compensate for the compressor coming on and will idle down when the compressor turns off.

In the mornings after a cold start, it will sit happy in park and not idle up at all. Idle will drop 100rpm or so when you click into drive...

Any ideas?

Had the car mildly tuned just today, and the idle has risen to 1400-1500 if you are in park or neutral.

In drive the idle is perfect 750-850.

Mine behaved like this when I added more fuel at the injector pump.
I had to back my idle off when I increased the fuel on the injector pump.
When you say mildly tuned, was the fueling adjusted at the injection pump adjusted?

Have you tried reducing the idle a touch anyway?

Mild tune, added a tiny bit more fuel down low (rotated the pin) and main fuelling.
The idle was high before this.

Problem I have is that the idle isn't high all the time...

I just started car and it is warm and idle is normal..

I will knock the idle back slightly.

I thought it was maxed injector pump....So i backed some fuel out of it and it seemed to fix issue...or did it?

Now when the aircon pump comes on, it idles up to 1500rpm.

How do you adjust the aircon idle up?

Bump.
Anyone?

How do you adjust the aircon idle up?

There are a couple of bolts holding a bracket for the aircon idle adjuster on the injector pump. The holes on the bracket are slotted. Loosen the bolts and adjust as appropriate - or do what I did save weight and add power - get rid of all the aircon.
