car stalls when warmed up, wont start till cooled down
might be the ignition coil, check it.
could be a vacuum leak, a sort of deffective valve or sensor. I suggest to check your engine coolant temp sensor, probably defective.
I did plugs,wires, engine coolant temp sensor, ignition coil. No help. Then I cleaned the idle controller valve. that got it to keep an idle much longer but still occasionally stalls and if you shut it off when warm it won't start till it cools.
