V8 miss.

[1998GTS]

Hi Guys.I have a HSV VT Series 1 GTS which i had a problem with the other week,as it would turn over but not fire.Found out the coil **** itself,so got that sorted.Now i have a small miss when the car is underload,could it be leads,plugs bad fuel.or something else.Any help would be great.Thankyou

My guess is a bad lead or maybe a plug.

From first principles, if it wasn't a problem before then 1. it's either something that the faulty coil has caused or 2. something that has happened as a result of the coil replacement process.

1. There have been reports that faulty coils can damage the ignition module under some circumstances.
2. What else (if anything) had to be removed/replaced in order to replace the coil. There is very little clearance between the back of the Holden V8 engine and the firewall, and replacing the coil is a bit of a struggle. It may have been necessary to remove leads and other items which could have damaged the leads or plugs (as accentstencil has indicated).

well the bit under the coil packs is expensive but can be the cause of a miss

its a DFI whatever that is but it is on a V6 not sure about the V8

hope its just plugs or leads for you

could be any part of the ignition system, plugs, leads, coils.

Thanks guys.I'll go with leads and plugs first.

Could be a dirty fuel filter too.try it if the leads and plugs dont fix it.
