Engine Knocking Sound

[gldan]

I have a question about my 1998 Eighty Eight Olds LS model. today while driving my vehicle started to have a knocking sound comming from the engine, when its driving and idleing. i was wondering is this going to cost me major $$ or what could be the problem. does this car have knock sensors? any help would be appreciated

thanks,

dan

Welcome to AF, from here there is no way to tell what an engine knocking sound comes from, it could be a valve noise, a bad bearing or internal, drive pulley bearings and so on. Somone has to listen to this directly to give you any meaningful advice.
