My Twin Turbo has a misfire on cylinder # 4. Me & Mikey Bean had a look today to try and resolve it, so far we've tried changing coilpacks, spark plugs, PTU, cleaned up coil pack connector, can hear injector ticking like all the others.

 

Where can I go from here? Can someone give me an idea of what to try next please? Got bits kicking around if I need to swap things like ECU etc. :shifty:

 

Any input would be most appreciated thanks :thumbup1:

Nice one chief!

If anybody wants toi check an injectors firing in the car,remove the spark plug and injector plug,trigger it with a 9 volt battery and some wire,using a torch you will see the fuel atomising into the cylinder.

 

now that is a usefull tip.

Thank you Baz. Arrived today. Got a busy day ahead of me tomorrow. Injector to replace, awkward as f**k PCV valve to replace, last two spark plugs to replace (the awkward 2) and a puncture to sort.

No worries Dave. Have fun fitting it!
