intermitent missfire

[Finfon]

that goes away after a few minutes :crybaby: there is no emulsified oil in the filler cap or on the dipstick it doesnt over heat or lose coolant that i know of no whooshing sound coming from behind the dash i recently replaced the spark plugs with the correct ngk ones all gapped corectly what do you guys think could be the matter? im not sure how old the ht leads are i think i might replace them anyway every thing else seems ok
also its done this twice now both this month and it has rained every day almost would dampness affect these engines?
cheers guys

Dizzy cap also worth looking at, also have a look to see if the plugs are drowning in oil.

I've noticed the Karman Vortex can be effected by the wet as mine threw it's dolly out big time yesterday (Misfiring at idle ond on overrun & Stalling - was fine at higher revs) and then managed to effect a self repair and has been fine since. I will have great pleasure in smashing this bastard thing (along with the other 3 dead ones I have) to bits with a big lump hammer when I switch to the LINK map sensor full time.

Nod.

aye, as with all engines, damp is a definite cause of problems.. clean, dry your leads, dizzy and check for arcing. a dark evening is the best bet. fire her up and see if the head looks like a christmas tree cos of the sparks.. any sign of blue/yellow flashes around the ht leads and bobs your auntie..

Hi

Slightly drunk sorry, but just my 2p.....
on my gt4 everything was fine and dandy until it rained........ and then it started missing like buggery - over a period of a week or so i eventually lost 1 cylinder and replaced everythng in cost order from dizzy to rotor arm to plugs.......still misfired - replaced the leads........and robert certainly was my fathers brother, along with his faithful wife fanny!!! :)

Sorry guys,,,,,,,, anyway I hope you get the technical bit from it!!!! - sound s like leads!!!

cheers (hic) :happy3:

[gtstarga]
