Sometimes after i drive my car and turn it off the radio and everything turns off but the car will stay running, do i need a new ignition?

 

does this car have a engine swap in it. When I did my engine swap (b16A) into my 1991 hatch std, my car would stay running when key was removed. The wires in the engine harness were in the wrong pin locations. called hasport and they told me which ones to move.
good luck, colnago

 

Sounds like your ignition switch / wiring is screwy. Normally though, if your ignition switch is kicking the motor will randomly turn off.
