Car very hard to start in mornings with lots of smoke out the back.will fire maybe on 1 cylinder and cut out.as it gets warmer will fire on all 3 cylinders.and drive reasonably ok.codes coming up 16885, 16686, 16687,16684, 16685, 16705.linked to speed signal sensor, misfires, rpm signal. Think it might be timing chain problem as i know they give problems. Looks like somebody has already done work in this area as silicon around timing chain cover looks fresh enough, compression ok

Thanks Liam
