can anyone help me my car is a 98 wrx wagon imported this year.
when driving it through the gears i begin coming on boost sometimes it boosts to 0.8 bar dropping to 0.7 holding that boost then other times it goes all mad boosting to boost cut n other times it just spools up to a bar dropping down 2 0.5 then up again n so on, this happens with out taking off ur foot. im a little stuck any help is much appreciated. actuator maybe? boost solenoid? ive looked for leaks n listened carefully car hear anything un toward. cheers everyone

 

any fault codes? if not could possibly be the maf or ecu.

my wrx ra ecu was fcuked and kept hittin fuel cut.

 

Before getting your wallet out, do a search on here for how to clean the boost solenoid to see if that helps.
