If your distributor is not in right it will set this code. Align themark on the crank balancer with the mark on teh timing cover. Make srure the rotor on the distributor is pointing to #1 if it's not move it there then clear the code and see if it's still on. If I is then test the engine on RPM and if the rpm's read double then your crank sensor has to be replaced. If you fixed it originally and didn't clear the code you need to do that first.
