Diagnostic code p0300 help

[ross-lakin]

Hi all , had a problem with my car for a week or 2 now , just got a elm 327 diagonstic reader , i am get the error code P0300-Random/multiple cylinder misfire detected

any ideas what this could be ?

Not sure what my code was, But I had a misfire on Cylinder three.
Changed The spark plugs, Ignition leads and coilpack and this sorted it.

Sounds like a coil pack issue - Was the fault "Active" or "Memory"?

Just clear it and see if it comes back firstly

I'm assuming the car is running like a bag of spanners then? The usual suspects apply:

• Coil Pack
• Plug Leads
• Plugs

First thing to check before spending any cash is that the plug wells aren't full of water or oil. If they are this will most likely be the cause of the missfire.

Checked the plugs bout a week or so ago they looked fine , gonna try a coil pack then if not will try the leads
