I erased all codes successfully. I removed and cleaned the MAF sensor, cleaned the throttle body, and replaced the camshaft position sensor (CPS). I replaced booth ignition coils. I inspected the spark plugs and they are nice and brown, correct type and gap. I recently replaced the plugs, caps, and rotors.

I started the car and still had the same problem. This problem started after I pulled the instrument cluster for replacing a broken odometer sprocket, and the battery was disconnected for a week. In the past, leaving the car off for a week or more caused an initial shaking that cleared up after a few minutes of running. Now it just gets worse with warm-up. From cold start it vibrates, like it's missing a cylinder. The vibration peaks at around 1600-1800 rpm. Then as it gets warmer it runs more rough, finally stalls.

I read the codes in all pins and found the previously erased codes:
PIN 7 CODE 6, 11

I think the fault code table is telling me it's:
6 Starter lock-out/backup lamp switch
11 Fuel safety shut-off to LH-SFI control module

I am not sure I'm reading it correctly, or what to do about them. On page 47 of the document it says W124 should connect to a 16 pin connector, but mine is 38 pin.
