Turns out that the connector wasn't the problem this time. After I made sure that the connector was connected properly the engine light cam on again. On closer inspection I found that the spring that is in the top of the rubber boot that goes over the spark plug had broken. I shortened it and the problem was still there, so I replaced entire boot assembly and that fixed it.
Thanks for your reply.
