I've got an 89 turbo with a hesitation issue. It idles fine, cruises fine and with light acceleration does ok too. But when I want to get on it the turbo spools, but it falls on its face...hesitates hardcore! I sort of checked for a boost leak (noticeable holes and making sure they are connected!) I have an aftermarket boost gauge, and blow off valve. The yellow sensor that says Sensor ASSY Turbo Pressure has a hose connected to it, but it goes into a "T" and the other hose goes nowhere, (I plugged it up and my vacuum went from 10 to about 16 at idle) but it looks like the main hose is going to the blow off valve. The orange, brown and white connector is not connected, nor can I find it! Will this affect how my car runs? If it does where can I find where this plug goes?

Any help with this would be amazing! [IMG]file:///C:/Users/Owner/AppData/Local/Temp/moz-screenshot.jpg[/IMG][IMG]file:///C:/Users/Owner/AppData/Local/Temp/moz-screenshot-1.jpg[/IMG]
