My EF Ghia has a problem!

When I come to a stop say at traffic lights(still in D) the idle drops to around just under 500rpm- and sometimes it stalls- this is intermittent. It seems to only do it on GAS.

When the car is in either Park or Neutral it is fine and idles around 700-750rpm. I have adjusted my Gas idle screw- but its stil the same. And it is most noticeable when I first start the car and move off.

Other then this the car runs smooth, and returns fantastic economy on LPG- around 500'ks per 70'l's.

Any ideas??

Cheers

Check to see if you have a vacuum leak, also the ISC might need a clean.

See if the idles screw can or needs to be adjusted, also check the TPS.
