Ignition Coil Wiring 182

[tombernardhearn]

Hi,

Had the inlet manifold off, and just noticed the wiring onto the ignition coil. There's only 3 pins going into the pack, when there's space for a 4th. I would assume that each pin corresponds to timing of each spark plug firing? If so does this mean its running on 3 cylinders? Theres only 3 cables going into the connector so unsure if this is normal. Iv photos here for reference.

New here so hopefully hasn't been discussed before but couldnt find much info, ta

should be very noticeable if its running on 3 cylinders

Indicators being Noise wise, or lack of power or something else?

Had the car since decemeber and first time getting to do a bit of work too it, so may have not noticed. No expert or anything but felt ok to me

Probably a little late to answer this but the Clio has a wasted spark ignition so it only requires 3 connections. One for power and one each for the spark trigger which comes from the ECU. Cylinders 1 and 4 are triggered together and 2 and 3 together.

Ah, thanks for the info, makes sense! Much appreciated,
