Thanks for the tips, Yes I called the Kia, I was pleasantly surprised to find they existed after the one in Newton NJ went south...my prior source for parts. That's where I got the estimate of $800 for the computer, I'll try the fuel regulator then it's down to the dealer...I'll let you know what happens. After mucho searching still have not determined if there is an ignition module and computer on this car or just one computer. I found references to ignition module connectors making me think there is an ignition module. In my experience ignition modules (and wrong ones) can cause such mischief.
While sitting this car had mice in the intake, I took all their nest out and thought I cleaned it thoroughly, put in new filter, but I'm wondering if anything would go shooting into the intake plenum would that possibly make this happen.
