Electrical misfire cylinder 4

Posted in

Hi i have a Daihatsu Terios 1.3E 02. I have a electrical problem which is misfiring on cylinder 4.I Have had a diagnostics test done by two different people, the code comes up reading P0304 but still cannot find the problem however people say it may be a injector or a ignition amplifier which is located on top of the head. All wires have been checked on the coils and renewed the spark plugs and are all in working order.

Has anyone had the same problem can anyone help?

Iv'e heard something similar !!

I'm not sure i heard it on here though.

It was a misfire on a cylinder and all checks were done.

It ended up being the igniter box. I presume this is the new word item that replaced the old type coil.

They replaced this and it sorted it.

No promises but that's what I read.

Don't like the new shape Sirion much.Sorry.

Burned cap.

Not certain if yours has a distributor but it sound like the distributor cap's electrode on cylinder 4, is possible burned away.

I doubt there is a mechanical

I doubt there is a mechanical distributor, as I think it's the K3-VE engine. I agree with Bob it's possible it's a faulty coil.
