UK-POLOS.NET - THE VW Polo Forum

Alright lads , I've got a 1.0 6n2 polo spent a lot of time and money on it put it's bringing up a code 'p0301' Ino that's a misfire code I've put new spark plugs and leads and a new coilpack on it any suggestions what the problem could be?

Any luck with this have that problem too

Hi lads,

I got my 6n2 last October. It's showing misfire codes also, the random misfire one, and misfire in cylinder no.4 (Sorry I forget the codes off hand)

I've been slowly working through the list of possible faults as related to me by mate who's a mechanic.
I've also done a lot of googling to try and establish what it could be.

Here's what I found:
I could be :
Sparkplugs,

HT Leads

Coilpack

EGR Valve issue (because I got another error to do with the oxygen sensor, I investigated this)

Fuel Injector Issue

Cylinder Compression Issue

One forum I read, the guy had a similar problem, after testing the compression he found that it was a bad spring affecting one of the cylinders.

There it is, I'm currently at the fuel injector point, as in I need to test them. Once you get into the cylinder shenanigans things get more complicated (relative to my noobie level)

I hope this helps!
