Drop In Revs - almost stalling

[gadj]

Boost at idle is around -200 to -300.

Soundes a bit high - also, are the revs stable but the vacuum bouncing about a bit at the same time?

What rpm is it trying to tick over at ??

the revs are more stable now the throttle position sensor has been changed.

Idle was set to 800 for two settings, and 900 for the AC one. Not sure the difference between the two 800 settings, but I\'ve up\'d it to 900 - will see if that makes any difference.

The boost gauge is only bouncing between 200 and 300. Not much really.

Will see how it reacts on the 900 idle now when I get home. It always tries to stall as I reverse it into the garage.

Is there any downside to setting the idle at 900?

Aren\'t those symptoms similar to a blown apex seal? Stable revs, and bouncing boost gauge? I don\'t know how much a boost gauge \'bounces\' when an apex seal goes though.

you can always turn the heater fan control to position 3 as this raises the idle speed a little. mine is always set on 3 as mine stalled when going around a mini roundabout, just when you really need your power steering - needless to say i sailed straight over the damn thing - its never stalled since

The increase in revs just uses a little bit more feul !
