So this past week I finished up my manifold swap to an msd atomic airforce and I now seem to have a vacuum leak. I've sprayed the seals injectors tb ect. but haven't found the source of the problem. Could it possibly be the back of the intake something I've missed? I've also thought maybe the 102 tb needs the iac reset to it could that cause surging issues at idle and when at cruising speeds? any suggestions are appreciated, this week the cars going to a friends shop to get checked out.
