Help!

After running the car on the freeway on a warm day the RPMs will be very low once I exit and come to a stop. About 5 minutes after that the engine will finally stall. It will restart if I put the pedal to the floor and crank away. It continues wanting to stall unless I continuously give it gas. Once it cools down it runs fine.

I have had a tune up but it hasn't changed the outcome.

Any suggestions?

Thanks!

#1 the CHT is starting to go and its going rich
#2 the MPS is cracked and its starting to go rich-check it with a vacuum pump
#3 the idle is set when cold but should be set when the engine is hot

Add intake leak.....
