Hey guys, it sure has been awhile since i've posted; mainly because my car has been running in tip-top shape! Nonetheless, upon driving it this morning I noticed something rather odd about my car. Whenever I accelerate it sounds like an 18-wheeler; everytime I shift it sounds like a big ass diesel engine. It seems that his noise seems to correlate with the acceleration and rpms produced under the hood. My only thought is that I may have busted a vaccuum hose or the pump itself? That is if the N/A's do have some sort of vaccuum system. Either way, I took it to the shop and I was just curious as to what to expect. Thanks guys!
