While driving in 5th gear the other night I realized my engine was revved higher then it should have been considering the speed I was going. It wasn't until I released the gas pedal that the bov released pressure and I was able to continue in 5th gear this time with no high engine rev and I felt like I was back on boost. Would you say this is a bov problem and it needs replacement? Is there a quick fix or is it something else altogether causing this?
