Dirty air filter .... sounds weird ... but it does this on factory LPG models moreso when stopping quickly revs will drop to nearly stall point and regain.

Other than that ... I'd say your Idle Control Solenoid (I think it's called that) may be showing initial signs of dying. Not sure if it's a cleanable item ... or if it's just better to replace it or not.

Others will give you a better idea.

Might be an idea to spray some carby cleaner into your throttle body too ... it's probably oiled/gummed up ... the butterfly can some times stick a bit when gunked up too.

Check the filter as Mechan1k has suggested as it's so easy to do. If it's dirty, replace it. If that doesn't help, then give these a go.

1. Cleaning ISC Valve

2. Cleaning Throttle Body

If the idle hasn't improved, you may consider giving this a go.
3. Setting Base Idle

Cheers and all the best with it,

You got me! LOL!

I actually did write chief first, as I'm often mucking you 2 guys up! I changed it straight after, as I checked your post to make sure I was giving credit where it was due!

The car is running too rich at idle and the plugs arent burning the extra fuel to create enough engine vacuum.Also could be the tps going haywire and not referencing the correct idle voltages to the ecu which controls the isc module for idle speed
