I have the code for a crankshaft position sensor and a out of range code.. I already replaced the sensor .... any ideas... thanks

its a 1996 Z28

what code is it. did you do any work on car like intake or did dizzy removal.if timing is out. that will throw code for camshaft timing off.

yes , and the chevrolet delership did the timing , but they must have done it wrong , im gonna check with them... thanks
