O.k.,that was an issue on these.If you spray into the throttle body the fluid can work its way down the shaft of the throttle plate into the throttle control motor and throttle position sensor.The way that it needed to be cleaned is to spray onto a rag and take the rag and wipe out the throttle body bore opening the plate by hand carefully and wiping beyond the plate to clean out the carbon.
If you know for sure it is clean now most likely the throttle motor or throttle position sensor is at fault here with the throttle body needing replaced.It isnt allowing the throttle plate to stay open enough to allow it to idle properly when warm or intermittently.I have seen this occur before unfortunately and had to replace the throttle body for this issue here.
Once replaced you can relearn the idle position by key on for 10 seconds then key off for 10 seconds and repeat 2 more times then start the engine.
You can obtain a new throttle body from a dealer or local parts store ( as the local parts store may be cheaper) or even used for far less of a cost.I use http://www.car-part.com for used parts and they can ship it to you.
But if no codes are set I do suspect throttle motor or throttle sensor in the throttle body at fault with the throttle body needing to be replaced.
