Replaced the purge valve hose but that made no difference but given the damage I suppose it needed to be replaced. I found that when I disconnected the input solenoid on the right hand bank the 29cc and 29cd errors went away and the car ran really well without a misfire. I felt sure that this meant that the solenoid was faulty but when I replaced it with a new one the misfire, CEL and error codes (29cc and 29cd) reoccurred. When I disconnected the solenoid I got a solenoid disconnected error code but it did not generate a CEL.

You need to get the vanos timing setup tool and check the timing. Could be that your timing is off.

Troubleshoot, troubleshoot, troubleshoot.

If the engine runs smooth at an idle I would expect all cylinders are functioning normal at an idle but not under a load. Under load the DME could be changing settings because of cylinder one not functioning at reading DME expects from it. I would be sure I have thoroughly troubleshooted cylinder 1 before going on to problems that would impact multiple cylinders. Cylinder 1 injector might be the problem. Might be able to verify by reading the plug after putting load on the engine several times and not letting it idle after doing so. Sometimes all you need to do is add a bottle of Techron to a full tank of quality gas and the problem will fix itself. Potential problem with the injector was mentioned earlier and how to test for bad injector but don't see where that has been addressed. If it turns out to be a bad injector I would have then all 'rebuilt'. One is often an indication the others are not far behind. I think I would do a smoke test also.

Have you checked if your vaccum pump is leaking? I recently noticed a a very small oil leak right under it. Could be a vacuum leak as well. I plan on changing mine soon, the new o-rings came in.

For the last three weeks I have been running the car with the inlet solenoid on the right hand bank disconnected. Except for a slight hesitation under heavy acceleration the car is running fine. The 29cc and 29cd error codes have disappeared although have been replaced by a 2A63 (solenoid disconnected) error but this does not seem to generate a CEL. The car idles fine, no smoke. Brings up an interesting philosophical point. At what stage do you walk away?
Seeing I have bought them I think the next thing I will do will be to replace all the solenoids. Not sure why just replacing just one of the inlet solenoids makes such a difference. Is the solenoid on the left bank still operating?
Once I have done that I will reconnect all the solenoids and see if the misfire (and associated error codes and CEL return). From past experience I think they will.

I think I have fixed mine finally. 4 days with no flashing cel.

Although my plugs were only a year old done by the previous owner, after replacing everything possible just like you have I decided to try two new coils on the cyl 1 & 2 which were the only consistent misfires codes I got from random misfires.

Since replacing those two it's been running good.

Maybe they were faulty or went bad when the valve stem seals were leaking fouling the plugs.

Through my research the coils are pretty sensitive and even dropping them on the floor can damage them.

Did you ever make sense of your issue?

Did this officially fix yours?

I'm having nearly identical issue recently. Rough idle, hesitation on slow accretion, runs better when warmed up, seems fine at higher RPM. Multiple cylinder misfire codes.
