#1

my car while driving stalls out and dies only when the temp out side reaches 93-higher degrees. what would make that occur when it is hot outside.


#2

Often it is some heat-affected electrical part in the ignition system, like a crank position sensor or if it has a distributor the pickup coil inside it. Fuel pump relay also.

Do other electrical things (lights, radio, dash) still work when it quits on you?


#3

Yes everything still works. The engine just stall out after a stop and only in extreme hot weather with temps of 922- and above outside.


#4

At that point someone needs to fid out if the engine lacks spark or lacks fuel. The answer will lead to further diagnostic steps, or at least hunches.
