Man, I try to use OEM parts just for this reason. Going off of memory, I think I used regular Autolite's because Autozone didn't have the platinum's in stock. At the time, I thought that I was luckly by not having to spend the extra bucks. I did go out of my way and order the Motorcraft wires, they were only a couple bucks more than the no-name crap, I just had to wait a couple of days. After the "tune up", the CEL characteristics did change and I didn't clearly remember the stumbling before I messed with it. I had just gotten the car, so I just thought that it was there from the beginning. I'll check/change the plugs this weekend and get back to you. Thanks for the reply.
