Okay, my 88 GT is having wierd problems with the way it runs. I when at idle if you give it just a little bit, just barely move the pedal the RPMs drop and it kinda sputters. When on the road at sertain throttle postions the engine also sputters. Under full throttle accelertaion, the engine doesn't pull that hard at all. I put it back down to stock boost, but it still has these problems, the one thing I noticed is that the last part of the intake tubing that attaches to the TB has a pretty good sized leak in it. Is that what is causing the engine to run so bad? I am still showing 6 psi on my boost gauge. But you can hear the leak under the hood when the engine is on and idling. Any help is greatly appreciated. Thank you.
