Got home a few min ago put the car in reverse and shut the car off and the car was still running till i put the tranny in neutral. Then the car shut off.
Any ideas? It might be something simple but I have never had a car do this before.

Car
90 civic sedan lx dpfi stock
5 speed

 

maybe just bad ignition wiring.

 

i had a similar problem but mines a five speed, i just replaced the ignition wires (junk yard $7) and everything worked perfect

 

Mines a 5 speed also.
The car runs fine with the key off it doesnt act all chuggy like its delsing or anything

 

yeah i would just replace the ignition wires, try it keep us updated. good luck
