hey tr i was in my car today and for some reason vtec started not poping hard at all it was really weak, and the engine was struggling to get to a 100 more than the usual.. (d series hate 100+ lol).. then i start hearing this radaling noise coming from the engine.. its only when im about to shift no matter if i get on it, it does not raddle while is idling or while normal driving.. but every time my tranny shifts i can hear the radaling noice.. i have not been able to rev it hard while on neutral cuz its late its the first thing ima gonna do tomorrow morning,, but what do you guys think?? its not smoking or anything,,, lmk thnx
