alright guys hopefully someone can help me with this, iv been havin trouble with the boost on my car for ages now after much thought I decided to take it to an "expert" who after looking at the car and having a poke about told me the actuator had had it which I had been told before so I had it replaced and after looking at the old one it was definitley bust but still the boost still is'nt there, iv had 3 differant mechanics look at it now and still no joy. The best way I can describe is with the car running if you load up the engine you can seen the piston in the BOV fluctuate, not open or close fully or smoothly it kind of bobbles up and down as if the boost is trapped or not circulating fully, i need to know whats up so i can fix it cause im after selling up asap as i need a car for the family and the pulsar is immaculate apart from that so any help would be more than welcome, cheers
