P-code 1530 in 97 Boxster

[debster]

We could use some advice about the codes associated with my wife's 97 Boxster (the Debster) engine light coming on:

The Debster has these DTC's:

P-code 1530 on a universal code reader, per the Bentley service manual that's Porsche DTC 174, Camshaft adjustment, cyl 1-3

Details of the incident setting this code:

Speed 31 mph
2463 rpm
Coolant Temp 179
3.5% load

Short-Term Fuel Trim 1 0.0%
Long-Term Fuel Trim 1 0.8%
Short-term Fuel Trim 2 0.0%
Long-Term Fuel Trim 2 -5.1%
Short-Term Fuel Trim 3 -100.6%
Long-Term Fuel Trim 3 -100.6%
Short-Term Fuel Trim 4 -100.6%

Fuel System 1 Open 1
Fuel System 2 Open 2

There are also pending codes 1313, 1314, 1315, and 1319. Those all indicate misfires in cylinders 1-3, from the scanner and manual info.

The code was erased and returned.

So what have we likely got going on here? There are posts about camshaft timing chains and the manual goes into some about the camshaft positions sensor.

Any information is appreciated. Thanks.
