Lost, Need Help!!!

I have a 98 ZX2 with 148k, auto. I’m getting code “P1383 Variable Cam Timing Over-retarded (Bank 1)” what does this mean and how do I fix this. I’m not a ford guy, so I’m lost with this one. I’m thinking timing belt. Please help!!!

buy a timing kit and reset the timing. ensure you pull slack from right to left.
