Clean the contacts on your PCM board again. Just a little oxidation can interfere with the signal. It worked for me when I had the same problem!

Bet your dealer upgraded ur PCM to 2000 CUX2. If this is the case you need to send your chip in for a reburn. This just happened to me.

 

I called the chip programmer and I'm sending in for reburn thanks, I'll try one more clean then send, gotta get it straightened out, L too slow need speed!!!
