I am having a problem with the car starting and running fine and when it hits a certain temp it then after turning car off and then trying to restart its like the motor is locking up but as soon as i unplug the crank angle sensor and turn it over it is good so i know its ignition.Then you plug it back in the CAS and it will then start then u turn it off and it will cease up again .I have changed the CAS and it still gives the same problem .The car was running fine until i adjusted the timing by turning the crank angle sensor (CAS) .It is back to its original position and still is playing up .Any ideas would be appreciated.
