engine quitting after warm up

[chadsdc]

93 olds achevia seems to run fine when cold but after warm up it will die on the highway and will not start for a few minutes and then only runs enough to move about 20 ft and will also stall in the garage at higher idle

not giving me any codes

just replaced coil housing spark plugs and boots because of a miss problem but that cured it now it will stall

it is a 4 cly 2.3 dohc ant suggestions thanks

Sounds similar to what our 93 does.... did you check the idle air control module?

[chadsdc]

yes but it turned out to be the crank sensor
