Five cylinders??

[Fusion Boy]

Well its been a while... got the last issue sorted (reco AFM) and happy chappy for a few months. Recently my money pit has started to run on five cylinders when cold. It has always had a bit of a miss at idle when cold but has got worse of late and tends to run "on boost" or "off boost" till it hits operating temp. Any ideas peoples??

Check plugs and leads, when leads get hot they bend more so perhaps they are not fully making contact?

I am SO VERY NOT mechanical, so I am probably WAY off!

It'll be the plugs. Your plugs are fouled, reason it seems like it runs good when warmed up is because you have ran it for a while and burned / heated off the dirt / carbon. I have had that before when my car was not tuned properly and I had bigger injectors installed.

BTW where did you get your AFM reconed ? and how much it cost ? I just recently had to recon a 300ZX AFM and that costed $200.

Could be a faulty coil. They do that. I just moved them round on my car to see find the problem.

Did an exchange unit, $350 tow in, drive out inc. diagnostics and labour. Lost the contact no but get in touch with Fryline for the details. Figured it was prob plugs or coil packs. Maybes my beloved will get me a set of plugs for Xmas eh!

bugger bugger bum shit! I thought your car was gonna be happy ever after Guess not, but I hope the plugs work out.

I've just noticeed this problem in my GTS, but i don't wnt to fork out $180 on a set of plugs (repco platinum) do I need the platinum plugs? repco said I do, but I'm not too keen on the idea

[zapf]

The reason they use Platnium ones is that its a @$@% to get to the spark plugs in a GTS / GTST

They will work - but not for long......and a complete firetrucker to change...theres basically NO leads - so thats outa the question - I would aim at coil packs........

You DON'T have to use platinum plugs and in my view they are a waste of money, use standard NGK V -Groove plugs, $18 for a set of six and gap them to 0.8mm and you will be fine, they aren't that hard to change, takes me around 20 mins to do the whole job. Also, it may not be a coil, my GTS did the same and it was the ignition amplifier.

mine is doing the reverse to that..... when i start it runs mint go like 5 ks then sounds like a subaru and drives like hella lag(and its a non turbo) ive done the plugs in the weekend...thought it would be that...NO IT WASNT bugger

[=ByTcHS|AppA=]

BAAAHAHAHAHAHAHA.......sounds like a subby....sell ya car dude....

[lock_monkey]

IF I DRIVE IT JUST RIGHT SOUNDS LIKE I GOT LUMPY CAMS...ALL NOISE HALF SPEED.... IM EVEN HESATANT WITH RACEING ESCORTS NOW LOL

[moondog]

I feel your pain! It seems I had pretty much everything wrong with mine - and yeah, it really does sound like a Subaru when a cylinder (or two) are missing

[lock_monkey]

could it be the computer that is doing that?
