thanks george ive tried carb cleaner etc no apparrant leaks if you switch lights and hrw on revs drop to 800-900 switch lights and hrw off and idle stays at 800 as soon as you touch throttle back up to 12-1400 i think it could be the solus-pro not adapting correctly i wonder if any one else has tried there solus to readapt yet as its a fairly new machine i did go through to the expert mode with the guy from scanline and into channel 098 and channel 060 but the solus was not supported by that section the customer has car back now and im going to see what happens thanks paul
