Hi Guys,
My Honda Jazz 2005 1.3 GLI Vibe is jerking in low revs and from what I've found on this forum its time to replace the coil packs.
I checked the manual and my jazz has 8 spark plugs and 8 coil packs, there is a inlet and exhaust side.
I'm not sure if I need both or just one set of 4 (either exhaust or inlet)

I was looking at purchasing these
Honda CIVIC 1 3L Jazz GD GE 1 4L Ignition Coil SET OF 8 Inlet Exhaust Side | eBay

I know I could just replace the faulty coil pack but I might as well do it all at once now and save me the trouble later if another one fails, plus I don't know how I would go about finding the faulty coil pack.

Thanks in advance

 

Don't get cheap coil packs. They go bad really quickly or they don't solve your problem at all. I made the mistake.
And 600 AUD? That's a lot of money! That's even a 100 dollars more than what OEM coils would cost you (over here).

 

Do I need to buy all eight?

The ebay link are the the Hitachi OEM ones, they are not cheap thus why I want to see if I can get buy getting a set of 4

Any help?

 

I can't say how long coil packs from other brands will last, as I only changed mine 2-3 months ago on the missus' car. I bought them from Repco - $90 each. Can't remember what brand tho, but it did solve the jerking issue.

Ok yes the 1.3 has 2 plugs per cylinder. Not for the exhaust stroke. The engine needs fresh air in to mix with gas to burn in the compression stroke. Honda did this to reduce pinging and detonation in the 1.3L. I would change all coil packs or you'll really be doing a searching game trying to find out which packs are failing and which are good x 8. I hope this all makes sense or I can opine even further. Was trying to keep things simple.

 

Thank you, I went ahead and bought all 8 yesterday. I should get them in the next few days, hope it solves the problem.

 

I hope so too, lol! That's a lot of money!

 

Right-on. Let us know.

 

Replaced all 8 coils and the problem has gone away. Problem solved.

 

Coil packs are very expensive, Usually its the rears that fail, to test each one disconnect one at a time and drive it, if it no longer miss fires you have found the bad coil, connect again at it will miss fire, remove earth lead from battery to reset the engine warning light after test,
