Hi

Seen a few posts about this. Overview is misfire/runs like crap/engine management light on/no power/shakes etc..

Plugged her in told me misfire/coilpack

changed plugs and coil pack and now saying Injector fault / short circuit to live.

Sounds like a few others have had this similar issue. is it likely it is the injector or is there another solution?

Injectors are hidden away and look like a big job to get too. anyone had this done and have examples of costs involved.

thanks for any feedback

Do the coils and injectors share a common loom? Could be the wiring on both is compromised and while working on one you physically disturbed the other.

Not sure if they do share a loom but when changing the coil pack only had to unclip it with very little movement so I think unlikely anything else where would have got damaged. Can’t physically see any damage

I was thinking there might be damaged insulation somewhere which could lead to faults when the loom was moved - not suggesting you chopped into the loom yourself.

I had a 206 in a couple of years ago where the customer had fitted plugs and a coil pack but still had an intermittent misfire and codes for multiple injector faults. I eventually traced the problem to a faulty-cheap!- coil pack causing the misfire and spikes in the ecu. As GreenV8s has said, check the wiring and multi plugs thoroughly too.

Youngest's 2 litre 307 had this - "Overview is misfire/runs like crap/engine management light on/no power/shakes etc..Plugged her in told me misfire/coilpack" - with the same codes (Peugeot Planet).
Cured with Valeo coil pack - about twice the price of the cheapies.
