I have a Ford Focus 1.6 LX 16v 2004 MK1. I went away for one month and after I returned the battery was dead. I charged the battery, started the engine and took it for a short drive. I noticed it was chugging a bit so I took it for a long and fast ride thinking it might be moisture but the chugging still persists. I bought a diagnostics reader which gave out a P0302 (cylinder 2 misfiring) error code.
It was absolutely fine before I went away. Could it be the fuel injector has got clogged?
I swapped over the ignition lead & sprk plug but still reads the error from cylinder 2.
What should I try next?
Thanks and hope you can help.
