When I say “swapped” I mean swapped position to see if the error code changed but it didn’t, still 29cc and 29cd (cylinder 1 misfire, multiple misfires). Mine idles fine but is definitely more susceptible to misfire when cold although yesterday did it when hot. I will check out the throttle pedal, oxygen sensors and brake servo and hose. I did replace both the “o” rings on the brake vacuum pump to stop an oil leak but no change. I thought an oxygen sensor fault would produce and unique type of fault code.
