replace car computer with home computer?

no, two totally different types of computers.you need the prom inorder to run the engine and transmission systems

Yes it will. A home computer has 10 times the computing power as even the most complex car computer. Just get an inverter and plug the computer into it.

First, get a second opinion. It's been my experience that most vehicle computers are replaced as a last resort, when the actual problem eludes their diagnosis. If it turns out to be a shorted or defective PCM, call around your local salvage yards and see if they have one - it will cost you significantly less.

Your home computer will not work - unless, perhaps, you can get Bill Gates to program it for you and add the necessary interface.

Definitely will NOT work as the car computer is built and programmed specifically to run a car, while a home comp. is much too large, and knows very little about running cars.
