AUthree

Hello all, wondered if anyone might know why my AUIII six is missing or checking under acceleration? Is it as simple as dirty injectors or something more sinister. Thanks Dave

Hi Dave
You probably need to describe your symptoms in more depth to make an accurate diagnosis but here are a couple of pointers anyway. The most common cause of misfire on all AU are the ignition leads braking down, specially No 4. This will be more noticeable under load and it will get worse as the engine temperature increases. Having said that, depending on service history, mileage, etc you could also have a blocked fuel or air filter, worn spark plugs a coil pack that's not working properly or a fuel pump that's on its way out. Start with the basics (filters, plugs and then leads) and go from there.cheers

Thanks Marc,
I have just had a service so the plugs should be right, I asked them to change the fuel filter so that should be right, I'll have a look at the leads next.
Car is 2002 with 105,000k's on the clock.
Thanks again for your advice.
Dave
