hi, i'm still fairly new to the 300, i know nothing about them to be honest:(

i've got a 1990 tt, and when it gets warm it sounds/feels like it's running on 5 cylinders. when it's cold it's fine, apart from cutting out from time to time!

i'm going to change the plugs at the weekend, to see if this helps, but was wondering what else to look for.

thanks in advance.

Could be any number of things. Connectors are a common problem, mine had a similar problem which turned out to be a connection to one of the fuel injectors.

Coil packs can also cause this problem...

first of all when its warm and running rough go along all the coilpack plugs and pull each one and you will hear the revs drop and when you pull one and the revs stay the same theres the problem :)

Hi mate, i had the same thing with mine. I used to pull up at the lights and it would stall. It turned out to be lime scale on all of the injector connectors. Gave them a clean and i've never had the problem since.

sounds like 1 of the coilpacks are gone.

 

 

when warm they lose resistance.

 

 

when cold, regain it.

 

 

find which cylinder/coilpack it is, try swapping it to another cylinder. if that cylinder then doesnt fire, you know its the coilpack

just wanted to say thanks for the advice. i took everything apart, cleaned all the connections etc, put it all back together and hey presto, back on all 6:-)
