misfire

[Jonny112]

Just got some new ht leads from euro car parts and cars misfiring at idle :s any ideas ?

Did you replace one at a time ?

 

[M26]

Did you replace them in the correct order?

 

[Jonny112]

Yeah

 

[montana]

What about the coil pack? I would be looking at that next .... Did you replace the leads because of the misfire ?

 

[Jonny112]

Coilpack is only around a month old only changed them as they have never been done

So did the misfire only start after changing the leads? Need a bit more info.

Im guessing you changed the leads because there was already a missfire?

Have you replaced the plugs aswell?
I had a missfire anf after replacing the plugs and leads it was sorted
