ok guys i searched a little here and at AW but it began to al look the same. heres the dilemma. i was driving back to work from lunch yesterday, and all of a sudden i went in to limp mode( usually bossting 18-20 but now only boosting 5) so i got back to work and searched on the fix. well i figured when i got home id check the hoses and perhaps clean the maf and go form there. well i got off work and went home, well for about 3 miles of driving i was in limp mode. stopped at a stop light, it turned green and i go. well whata ya know, im boosting 18-20 once again. the car ran alot smoother again, when it was in limp mode u could fell somewhat of a back pressure when giving it gas. soon as it came out of limp mode it felt torquey again.

so what caused it to go into limp mode, and then come back out?

pressure beilt up in the lines? dv acting up?

Well the dv could have been stuck open or the ecu held it open for that period of time since the DV is connected to another valve that the ecu can control.
