Here is another weird thing thats come up on my car in the last few months. When I turn the key off, the car will continue to run, not all the time, just some times. Some times when I turn it off, the power will shut off and turn back on (lights, fan). The 1st thinking was the lock cylinder but here is the weird thing, if I turn the car off and it keeps running, or I turn it off and the power comes back on, if I put it in reverse the power turns off like normal. Something tied to the reverse lights maybe? Anyone here of this before?

 

Never heard of that... but I'm sure you could easily fix it, just look for an exorcist.

 

it's called dieseling a gas engine

no, its not dieseling, the power is not cut so it runs the same as key on
