Hi all,
The past few days the car has been chugging occassionaly (sounding like wrx). I changed the plugs back in october and had the EMB tuned everything was fine. So i thought plugs may be fouled, pulled em out gave them a tidy with wire brush. Now the car is in limp mode not revving past 2krpm. coilpacks have brittle cracked plugs but are connected in fine havnt had an issue with that before.
Diagnostics is giving EFI NG: errors 14, 21, 25, 42, 52. I didnt reset the ecu to clear up preexisting errors as it didnt cross my mind at the time but will do so when i get back home.
Im not sure where to go from here, any help appreciated.

I had a error 14 code a while back. It was a coil pack connector that was faulty. While the engine was chugging, I disconnected a coil pack, each time the engine would die, indicating that the coil pack, connector and spark plug was ok. If engine continues to run (chugging), that's your faulty coil pack, connector or spark plug.

Error 14 has been cleared, was a faulty connector. Ive replaced all the connectors. Spark plugs should all be fine as they were all replaced. Coilpack shafts had cracks in them so were probably arcing to the head. Ive covered these in double walled heat shrink shown in the pic below but am still getting intermittent misfiring and chugging. There are cracks along the screw tabs on the coilpack housing, would this also cause sparking issues?
