Running rich when warm

[LeD ippen]

Ok here goes

Driving home after dropping off some stuff. all of a sudden my car ran on three cylinders. found out my injector was bad after having to recheck the ohms a few times. replace with another injector found it it was stuck open >.>. went to junk yard next day got another put in. now it runs on all cylinder but when it get hot it runs really rich where it fouls the plugs on all cylinders. i check the coolant temperature sensor ohms read good and changed it with another sensor. same thing. then my boss told me to change distributer. had one laying around changed it still same bought a new one too. it runs find if cold but once it warm even a little it starts. compression is 175+ on all cylinders wide open throttle.

ah also this was automatic motor swapped into 5speed but was running fine for a year
