Regarding the eractly up and down idle is because of the P06. I know because I haD the same problem with that ECU and I swapped in a P2T and now its idle'n perfectly.

Why aren't you running a stock ECU?

Is the Po6 chipped or is it stock? If its stock it probably will not run right since the 99 si is a dohc vtec motor. If it is chipped, what type of program are you running?
