spark plug leads

Hi all I own a 03 wk statesman, It’s been idling rough between 0 and 1000 revs and hesitates a lot when traveling at a 100kms and trying to push the accererator between 1000 and 2000 revs, the car also throws Check engine warning light when idling for 5 mins then goes away if I start driving...

Just purchased new spark plugs (ngk) and new leads(eagle) and i was wondering if I need to buy heat shields for the leads or they don't need them? Thanks

Hi all im new to the page and owning a commy, I have a 97 Vs i recently noticed a miss when driving under load, I changed the Leads yesterday and it didnt change ...im about to change the spark plugs today, Has anyone got any more insight into what may be causing the problem?

hey just got a quick question. i did a bit of work on my vl yesterday, just a few things that involved replacing the rocker cover and putting alloy intake pipes on. all went well except when it came to reconnecting the spark leads i mixed the back 3 cylinders up... and cant seem to find anywhere...
