hey guys. Having a problem with a 99TA 6.0 block stock bottom end prc heads ms3 cam 4000 circle D. it was running like a champ for a few months after the swap. Did a good burnout the other day and now the rpm surges at slow cruise speed. WOT is still great. just when you slow down to a stop like at a light or stop sign.rpm will hunt up and down. Any ideas? things to check?

thanks
