I know it's been awhile but I've been real busy lately. I just put the stock pcm in tonight and drove the car around. Seems ok but I'll have to drive it some more just to make sure the P0053 doesn't come back.
I lost Cruise Control immediately after I put the Overkill PCM in and now with the stock PCM back in CC still doesn't work!? Does swapping PCMs have something to do with this?
