i suddenly cant boost past 1 or 2 psi!!!!!!. i dont have a vacuum leak because i can still drive the car and there is no prob with the idle, i just cant boost past 2 psi. i am thinking that my wastegate is stuck open but does anyone have an idea what just happened because if this is not the problem i am stumped!!!!!!!!!!!!

 

Check all your plumbing connections. I was out with the car one day and had a Mustang pass me and figured I'd let her run a little. When I got on it, it felt way slow and I could hear the boost leak. Turned out to be the connection at the BOV. It would idle and drive fine, but would leak off any boost over 1 or 2 psi.

 

agreeed sounds like a IC pipe blew off or a coupler broke. if you have an internal waist gate thats easyenuff to check with a visual inspection of the actuator rod.

 

well i checked everything and didnt see anything that would cause the problem. i had installed a sub and two wires from my AFC had been melted together by accident do to the heat from the back of my stereo. is there a possibility that i might had ruined my ecu??? i looked at the waste gate actuator and is appears to be in the rest position but can the gate inside the turbo remain open even if the actuator is retracted.
