Replacing electric valve of air pump for vacuum control
Hi all! Recently I found that my x' engine roared when in low speed (below 40KM/h and in gear 1 and gear 2, sometimes gear 3) when pressing gas pedal, it sounds like a diesel engine. But engine runs fine, although it always roars. The transmission also runs fine. Hence my guess is that the electric valve of air pump for vacuum contol (part number: 11741742711) is about to fail. Just wish some experts here can give any idea if my guess is correct and how to replace the electric valve. Thanks for help!!
