If you didn't set the CMP offset, then that is probably what is triggering the code. It could also set if the distributor is off a tooth, but it's usually the offset being out of range. I'd start with setting that.

You'll need either a good scanner or can download an app and use a bluetooth OBD adapter to read the offset.

Loosen the hold down bolt on the distributor and turn the distributor until the CMP Retard (as read by the scanner) is zero degrees (plus or minus 2) at around 1,100 rpm (but no less than 1000). Tighten the bolt down when it's at zero and you're done. I believe that code sets when the offset is off by more than 14-degrees.

For Android, I've used DashCommand and CarGauge Pro. For DashCommand you'll need to download their extended PID for your specific model. Total cost for the app is around $40. You'll need a Bluetooth adapter for the OBD2 data port. I used a BAFX 34t5 which was around $20 on Amazon.

I couldn't find an OBD adapter that would work with an iPhone app, so bought a cheap Android tablet and used it.

CAMSHaft correlation error. the crank sensor and cam sensor aren't hitting TDC at the same time. In older terms the distributor timing is off. Best bet is to carry it to a place that has a scanner to line the sensors up.

It is possible that the rubber on your damper has slipped, which throws the timing marks off. It happened to my truck and the symptom was an engine that sounded fine, but had no guts.
Instead of buying a new damper, I just used a tachometer to adjust the distributor. You play with the distributor until you get maximum revs. Take note of when the revs decrease on both sides (counter-clockwise side and the clockwise side) of the distributor rotation. Set the distributor in the middle of that range. The engine should be able adjust itself from there. It won't cost anything to try and see if that is the problem.

Has anybody done this themselves? It looks simple enough. Just need some clarification on what he means by spark straight up
