hi all could someone tell me if this is correct, my 2 port boost solenoid is ticking on low revs and when I need some boost in 2nd or 3rd gear im getting hesitation then it clears ,seems mostly when my solenoid it ticking, is this correct or do I need to look elsewhere its a v3 sti, many thanks

 

when i had a hesitation problem with my 02 wrx it waas the air flow sensor playing up, hope this helps
