I have an automatic, 2005 PT Cruiser with 62000 miles. It runs fine while I am driving. But after the engine is warm, It wants to die out on me when I sit at a stop light or stop sign for a moment or two. If I need to drive very slowly for a bit, like in a line of traffic at a stop light, It starts running a little rough then wants to die when I come to the stop. I have taken it to the dealer and a different mechanic. They did not find the problem. The dealer replaced my plugs, wires, air filter, pcv valve and I keep the oil changed as scheduled.
They hooked it up to a diagnoses machine and they said it showed no codes.
I am afraid to drive for any distance and need to get to work safely each day. Any idea what I might suggest to them to look at? Please help. Thank you.

Thank you for your donation

I would be looking for a vacuum leak or a faulty coil, both will cause the type of problem you have and the coil will not trigger a fault code. the vacuum leak would if bad enough, but a small leak may not and could up set the idle mixture enough to cause idle problems. i would lean towards the vacuum leaks at this stage.
