Hi

I have been investigating a Cylinder No 1 misfire.

Yellow engine warning light constant or flashing

Engine starts no problem but idles a little lumpy

When driving there seems no loss of power

So far I have replaced air filter and all spark plugs.

I have also swapped cylinder No 1 with cylinder No 2 fuel injector.

I have also swapped cylinder No 1 with cylinder No 2 ignition / coil module.

I have cleared all codes but still get obd P0300 &P0301.

I want to try replacing ignition lead to No 1 spark plug but i have been unable to source a replacement, anyone know where I can get one from??

Any other ideas regarding this fault would be a great help.

Many thanks

Phil

Hi Igormas

Thanks for reply

And yes I have cleared all codes (I have cleared all codes but still get obd P0300 &P0301.)

NB

The ignition lead to Spark plug one is the wireing harness to the ignition /coil module

Must read slower!

If you've swapped all the components and the mis has stayed with No1, you need to do a compression test. Just make sure there are no leaks around the inlet manifold. Spray some WD40 around it and see if it revs up/smooths the idle out.
