I have a 1993 WRX and it has the occasional misfire.

So I phoned up a breakers yard and asked them to send the appropiate coilpack.

As you probably guessed I have recieved the single coilpack and not the 4 individual HT leads with each coilpack on them.

Is it easy to convert them if I put MY99 HT leads onto it? What about wiring at all?

Thanks!

You can wire in a MY97+ or MY99+ double coil pack thing with relative ease.

You have to remember that these cars use "wasted spark" - each coil sparks 2 cylinders each time - one just doesn't have fuel in it...

All you need to do is connect (from memory, so please check with a wiring diagram!!!) wires 1 and 3 from the ignitor block to one input to the coil and 2 and 4 to the other, then put the HT leads on the appropriate plugs I shall leave the specifics of exactly what goes where to you... (because I'm lazy )

I know Tone Loc (amongst others) has tried this when he had coilpack issues and found it quite successful, although he's since returned to using coilpacks IIRC.

Nice one cheers!

Will check diagrams though!
