KV6 really rough running

Hi All,

I have been asked about an issue with a 2003 V6, It spluttering and running rough with lack of power.

The ECU shows a misfire on cylinder 6 error code.

Putting injector cleaner through it seems to have improved the running for a couple of days.

Sometimes turning it off makes it run a bit better.

Apart from plugs, leads and injector, what else could be the issue?

Thanks

Valves sticking perhaps ? Just a thought Dave......

Did you try swapping the objected with another to see if the problem moves with the injector ?

Spark plug or HT lead. A failed injector usually shows an open curcuit error.
