I'd try and pick up a set of 2nd hand injectors, mine was misfiring and i did the same as you, leads, coil pack etc and then i got a set of injectors off here for £25. Swapped the whole fuel rail over and misfire is gone

Shall try that thanks for the reply

If you have a multi-meter to hand switch it to read resistence and put the probes across the two injector terminals - Let us know what reading you get.

changed injectors and cylinder misfire code on diagnostics has gone but still s**t on idle
