Rough Idle in Drive

[brettj]

Hi All,

I haven't posted in a while because my 75 450SE has been in the shop getting some major work done. I've had the trigger points, timing chain and,cam shafts replaced. The distributor , air conditioning system  and even the dash clock were rebuilt. The car runs much better now but I'm still having a problem with  rough idle when the car is in drive. I'm also experiencing hard starting cold and hot. I was thinking that I may have a vacuum leak causing the the problem. Does anyone have a diagram of the vac system under the hood and dash? I've already replaced all of the vac lines in the doors and trunk when I had the vac lock system rebuilt. If its not a vac leak what else could cause these problems?

Thanks,

Brett
