My car runs normal most of the time, but every now and then when you hit the gas, it will start sputtering and the Tach gauge will just all over the place. It will have a loss of power and feels like it is not getting fuel. It is a 3.1 V6, 98 olds Achieva..... no engine codes pull up, one suggestion was crank sensor.... could it be this or any other problem.... I could use all the input possible... Thanks

The Odd this is that it's not throwing a code, being OBD II is should throw a code if it has been misfiring.
