My dtc lookup Say's;
P1201, is manufacturer fuel air metering.
I'm not quite sure what that means, but that is the message displayed.
P2001= NOx Bank2 Trap Efficiency Below Threshold.
I don't know what that means either.
P0020=Camshaft position actuator A-bank 2 circuit malfunction.
P0353=Ignition coil C Primary/ secondary Circuit Malfunction.
I have had to replace a camshaft actuator on a 98 with in a year ago, but it didn't feel like a solid miss, if memory serves me right. But it may make sense, that it could cause a coil error, because the cam position sensor tells the coils, when to fire. A 1201, could be the raw unburned fuel from that cylinder causing a rich reading at the 02.
I've never had quite that combination, but I thought I would tell you from the dtc lookup software exactly what it said.
I would also look for wiring work that has been done by rodents. They love the taste of our wires.
You've switched the coil , and no help. I would read up on the cam position sensor and actuator, and check for damaged wires.
Post up your findings please.
