Could this (code P0302) be due to recently having cylinder head gaskets replaced?

Question

Recently had cylinder head gaskets rebuilt and replaced due to oil leaks that were causing smoke. Immediately had issues with ERG diaphragm and had that and solenoid replaced.

HI there

It is possible, if the heads weren't torqued properly, however the fact that the light is blinking usually indicates is an electrical issue. Faulty ignition coil or possible plug wire problem. I would start there and see if there is any improvement. It's possible the plug wire has fallen off the spark plug. These are in a tough area to get to.
