Hey anyone in or around London that's a tad handy with diag on engine fancy coming down on sunday and helping me diag a few things main one being why shes running on 5 I cant offer anything in the way of cash atm as I blew the money I had left this month on paying for the car ha ha. I do offer loads of tea and biscuits and a good laugh though ;-) someone that has conzult would be awesome aswell but beggers cant be choosers right... Anyways I know im being cheeky but you never know someone might be at a loose end

You tried going round and unplugging the coil packs 1 by 1 mate?

ill start that this weekend but im not really sure what im looking for if im being totally honest

When you pull one plug off you'll hear the engine note change as the revs will drop a little. Plug it back in and you'll here the revs go up slightly. If nothing happens then that's might be the cylinder that down.

 

I would suggest going round all of the connectors and giving them a good clean as the first thing to do

It could be spark plug, coil pack, injector, wiring harness or just green corrosion in a connector....... It might be worth doing a compression test at the same time as other bits......

If I was free I would pop up... But have loads on this weekend.... sorry...

I'm always up for helping a fellow Z owner but I'll probably be too hungover this Sunday

I would have been up for it mate but I'm afraid I'm out all weekend.

 

Though I've had this problem twice before and it's always been a spark plug for me. Check as described above...I'm a noob and it was easy enough for me!

 

Good luck and hope you find the problem!

I would have happily come round had I have lived a little closer.

agh its ok guys I think ade checked all the plugs and what not when he first found the problem

any other time though ;)

So did you find the problem?

anyone down for this sunday . I wanna start work on her this week so would be nice to have a helping hand

Ok so narrowed It down to cylinder 6 that is not working. I check the connectors and they seemed fine no green corrosion no lose wires or visible breaks. Whats next to check on this cylinder.

How did you narrow it down, by pulling the coil plug??

Yeah pulled each plug and listened for the engine note change. 1 -5 significant change of tone pulled 6 and nothing

Ok, now swap number 6 coilpack with one of the others. Try pulling the coil plugs out, one by one again. If the problem moves to the swapped coil pack, you know the the problem is the coil pack.

If the problem stays at number 6, try swapping the spark plug with a different one. That will then eliminate the spark plug as the fault.

 

In my experience it's always either the coilpack or the spark plug that is the problem.

Good luck

I'd gladly come and have a look, but you're a bit far from me. Sorry

ty mate that's a great help.

As "Evilanger" says, this is the correct way to eliminate a coilpack and plug...... But if you still have the symptoms at No 6, then it would point to an injector. If this is the case, you then need to check for resistance or continuity at the injector plug. (I can never remember which it is...lol) Do a search on here for the correct reading.
