Misfire

[chrisniss91]

I have just seemed to pick up a misfire It happens when i boot it between 4krpm upwards. Any ideas :?: Could it be a fault with my Power FC as my idle is still abit nutty

 

[andygtir]

spark plugs? did you get a colder range and gapped correcly for the boost?

 

[chrisniss91]

I had the HKS iridium plugs put in with the Power FC 2 weeks ago. The car was fine until now

water in the plug hole number 1 :?:

Could be i'll check later What about leads :?: Could they be at fault as i havent had them changed :?

 

[GTIR-LOZ]

yeah could be if you have a mulitmeter you could check the resistance in the leads, not sure what the reading is suposed to be though but i would check for water first had it happen to me a few times

The norm is water in plug 1.
Water get down the side of the lead and fooks the plug up.I find with the HKS ones that once the plug gets wet it fooked for good.
Do you have the vents open in your bonnet, if so block it off.

i have had water on my hks plugs twice and its still good as gold

 

[chrisniss91]

I have taken the vents off the bonnet but i have a sparkplug cover which covers all the plugs. Is it possible that the water could of seeped under and fooked one :?:

 

[GTIR-LOZ]

not likely, thats the idea of them to stop the water getting in
still worht checking though its only a 5 minute job if you have a front mount, if not id suggest twatting a set of leads on her, and maybe a fuel filter if that has not been changed recently
