Does anyone have any info on this? Don't pull any punches, if these are crap let me know.


Did a Search but not any real good results.

I've been throwing ccm 41 and ecm 42 codes, car intermittenly runs like hammered dog poop. I'm no mechanic by any strech of the imagination, but I wanted to try to figure this out on my own if possible.
I took the ecm housing off and this is what I found, when I first looked at it the side prongs were sticking out so I reached in to pull the chip and it wobbled when I touched it, so I thought I would just try to stick it back in the way it was supposed to be and it went in real well, the side prongs went up and are now in the proper place holding the chip in very sturdy. I started and drove the car, it seems to run great.
Could I have gotten LUCKY?

If you're lucky, yes. Keep your eye open for codes. 42 = ICM. But, a loose connection to the computer could throw these same codes.
