check block 032, if your part throttle trims are really negative (rich), it's a vac leak...
imo. 8^)
Whenever I've had vac leaks, my idle trims will go lean and my part throttle will go rich.

every setup is different...
Is very difficult to say what is your specific target for part throttle and idle but I'd be comfortable with part throttle < -10% and idle anywhere from ~+1.5 to -1.5.
