Hi there,
our vt executive is missing when we're driving along. We've checked the spark plugs and leads. Can anyone help?

How can it be missing if you're driving it? I don't get it..

miss firing?

If it's not plugs or leads it could be coilpack or injectors, but mostly it's leads. How did you check yours?

COuld also be bad fuel, pulsing fuel pump, bad fuel filter...

replace your plugs....its only 50 bucks......sometimes the insulator can be cracked and you lose spark straight up

$50?? WTF.. I paid $18 for my plugs..

What plugs are you using? And I would suggest just changing the leads also.. If you don't notice a difference, keep them for next time..

Very odd on an EFI car though if the plugs and leads are fine..

It's not on LPG is it? Because those are very common problems with gas..

hey shounak, i buy my plugs new mate, not secondhand sorry, that was a cheapshot.....i use bosch super 4 plugs.....they are pretty damn good....i know a lot of people think about spark exposure to the incoming fuel/air mix which the super 4 hinders this a bit, but the plugs on my engine showed a good spark between the electrode and the 4 earth pins....has good spark exposure on the end, much like a centrefire boat engine plug....
