power problem

[Rick Cone]

Hello, just signed up!
   
  I just bought an 89 200 avant quattro with a 10v turbo, 5 speed.  It had sat for a year and a half before I bought it.  Overall I really like the car; it only has one problem.  It runs awesome at light throttle, but when you give her the berries, it falls flat on it's face.  In 3rd 4th and 5th it really hesitates all the way up.  It's like it has more power at light throttle than at full throttle.  It is most pronounced as soon as it hits boost.  But I get full boost, so I don't know what's the matter.  I've replaced plugs, air filter, cap and rotor.  Wires looked good and I heard these cars were touchy about wires so I'm ordering a universal set of MSD wires to make a set out of.  It seems like the fuel pump is noisy too.  where should I start looking?  I want to get the ecm done, but first I need to iron out this problem.  Thanks for your time!
