I thought I would do an error check to see if 29cc and 29cd were cleared. I found that they were cleared but had been replaced by 2A63 and 2A64. I checked on these two errors and finally found out they were caused by me forgetting to connect the electrical connections to the solenoids. I connected them which cleared 2A63 and 2A64 but the original error codes(29CC and 29CD) are back again along with the misfire/faltering. Back to the drawing board. At least I now know I can improve the running of the car by disconnecting the vanos solenoids. Is this conclusive evidence that they are faulty?
