P0340
This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.
P0355 Coil Driver Circuit Malfunction The problem might be with with the distributor itself. I'd check all the fuses etc... Use some contact electrical cleaner on the distributor connector. Also check if you hooked up the spark plugs correctly.
So all in all the entire distributor might have gone bad. Worst case.
