Right got my zetec t bk up and running but misses on number 1 on idle and slight load. Changed the plugs n leads and still the same. Engine just been rebuilt so cant understand it. Im thinkin dodgy head gasket or maybe a bent valve but engine was timed up perfectly and runs quiet as a mouse. I did notice some smoke but oil was slightly over full mark so could just be that or the head gasket never sealed and its lettin oil into the cylinder. Any ideas????

I would start by trying another coil pack

Have a strong spark from the coil pack if a remove the leads slightly and lead is sparking when removed from plug
