Idling Speed Very Low When Warm

[hitesh]

Hi All,

Wondering if any experts out there can help me with a Idling prob on my 1999GS300sport. I'll try and keep if brief.

When the car is warm and come to a stand still the idling speed drops to nearly 0rpm and hesitates for a little while. It's like as if the engine is going to stall.

I have taken it to Lexus dealers and there computers are not showing any error codes a all. The Engineers have driven it and cannot find a problem too.

They suggested it could be Throttle Control Motor but not a 100% it will fix the problem and this part is over £1000.

Has anyone experienced the same problem and willing to help me please.....

Regards

Harry
