Hi Guys and Girls
Can you please help with this problem. My hilux miss fires on a spark plug gap of 008mm and runs well on a gap of 1.3mm is this the norm.
Regards
David

Re: Hilux miss firing
What do the manuals say should the gap be? I suppose you meant 0.8mm? 1.3mm sounds a little bit much but I have no idea what the spec should be normally it is around .06 to .08. How old are the plug wires, distributor cap, rotor etc?

Hi Marnus
sorry you are right it is 0.8 and the book says so, but I wanted to do a plug change and found that the plugs where at 1.3mm.Last service do 10000km ago.
Thanks once again

Re: Hilux miss firing
Ok but I am still not with you. Does it misfire if you set the plug gap to 0.8? It should not. If it does then look at the other things like the HT leads as there resistance increases with age making the spark weaker. Does your hilux have electronic ignition? Does it still use a distributor cap and rotor? Those parts also deteriorate with age and can impede performance and cause missfiring.
