It appears I have not one, but two Shelby LM's (part #P5249670) that don't operate correctly. One will start fine, but soon after begin to stumble, miss and run rich. The other idles at 2k and throws a power loss light.

Are these pretty much cores now, or can I do something with them? I know nothing about how this stuff is written or whatever, but would be willing to learn.

Thanks!
