I know with the Tweecer you gotta make a minor scalar change or the interface being plugged into the service port will throw a CEL.

I wanna think some peeps said that anytime you put something in that port you will get that CEL unless you make that change I was talking about.

You could go to the Yahoo Tweecer site and go all the way back to the first threads and I bet you'd be able to find some more specific info.

Not much help I know.........................
Its been so long ago and that is all I can remember

I had read elsewhere that this can be normal as well because of the chip. If she runs good, who cares.
