My 93 900 turbo CE has gone through alot since I got it two weeks ago. New Plugs, wires, distributor cap, rotor, BPV, Mobil 1, voltage regulator, exhaust manifold 9old one was cracked), air filter, fuel filter and cleaning of AIC valve. It is running much better but I still have a large hesitation before boost kicks in and boost seems choppy. I just tried the "wild boost" test and all of the hesitation was gone and it went easily into the red. (Only did this once for a second). I have ordered silicon vaccum hoses and grommets, but the old ones are there and don't look bad.

Anyone have anyone ideas where to look? When I get that hesitation, I do sometimes hear a vibrating sounds from somewhere. Cruise does work, but if I try to once acclerate button, it seems to accelerate for a second and then drop off speed. Maybe this is where my vaccum leaks is??

Thanks
Brian

P.S. Did new front suspension this weekend. Balljoints, tie rod ends, urethane sway bar bushings and Sach 112-102 shocks. Handling is great, very happy. No more clunks, creaks, or rattles, just nice firm ride.
