Ok my engine from about 35-65 will start to buck or out out then back in, causing a almost violent shudder. After doing some searching it seems this is realted to the O2 sensor. Well I just replaced it a year or so ago, but I do have an exhaust manifold gasket leak. The leak has been there for quite awhile and I havn't noitced this problem before but could it be causing this? Obisouly with the leak the O2 sensor won't be reading correct as the xahust will be elaned out correct?
