This unit is new to me, my sister in-law had the car serviced in Vegas and after that it began its hard start when warm deal what could the dealer have gotten out of adjustment to cause this, what happens is it will hit and fire then stall all in just a fraction of a second the next attempt will turn over excessively then try to start and stall, if you let the key stay on for as much as thirty seconds it seam to try to start, if you step on the fuel it just cranks away then it seam to catch slowly then brings itself to a point Ware you can get throttle response. I feel that we are looking at a fuel delivery problem when warm and only on start up when it is running it has great response. JNT
